For large-scale wireless sensor networks (WSNs) with a minority of anchor nodes, multi-hop localization is a popular scheme for determining the geographical positions of the normal nodes. However, in practice existing multi-hop localization methods suffer from various kinds of problems, such as poor adaptability to irregular topology, high computational complexity, low positioning accuracy, etc. To address these issues in this paper, we propose a novel Multi-hop Localization algorithm based on Grid‑Scanning (MLGS). First, the factors that influence the multi-hop distance estimation are studied and a more realistic multi-hop localization model is constructed. Then, the feasible regions of the normal nodes are determined according to the intersection of bounding square rings. Finally, a verifiably good approximation scheme based on grid-scanning is developed to estimate the coordinates of the normal nodes. Additionally, the positioning accuracy of the normal nodes can be improved through neighbors
In this study, we analyze security and quality of service (QoS) issues in cluster-based wireless sensor networks (WSN). Taking spatial resolution as the main QoS metric and limiting the security definition to data integrity and authentication, we present a control strategy to maintain desired QoS and security levels during the entire operation of a cluster-based sensor network. Besides, our proposed strategy considers some other WSN QoS attributes such as coverage, packet collision and system lifetime. It provides sufficient coverage by statistical means and minimizes packet loss due to collisions by employment of a slotted MAC (media access control) scheme. It also tries to maximize the operational lifetime of the sensor network by a power conserving scheme which make all sensors participate equally. In this study, we also determine the best tradeoff between security and spatial resolution ...
Heart Rate Monitors (HRMs) have become widely used since the last two decades. It used as training aid for various types of sports. And the development of new HRMs has evolved rapidly. Thus, in order to determine the exercise intensity of training session or race, HRMs are mainly used. Compared to the other indication of exercise intensity, Heart rate is easy to monitor, compatible to use in most situation and relatively cheap. Thus, it is most beneficial if wireless sensor network can be implementing into the system. Other than monitored their condition by themselves, this system may allowed a number of athletes being monitored simultaneously. Arduino-Nano board was used to interface with nRF24AP1 and XBee. The wireless sensor network consists of a microcontroller on Arduino-Nano board, nRF24AP1 and the XBee wireless communication module which is based on the IEEE 802.15.4.

Security in wireless sensor networks is difficult to achieve because of the resource limitations of the sensor nodes. We propose a trust-based decision framework for wireless sensor networks coupled with a non-deterministic routing protocol. Both provide a mechanism to effectively detect and confine common attacks, and, unlike previous approaches, allow bad reputation feedback to the network. This approach has been extensively simulated, obtaining good results, even for unrealistically complex attack scenarios.

An enhanced closed-loop power control method includes the steps of: setting an initial value of a power control variable; detecting a strength of a terminal signal and comparing the detected strength with a reference Eb/No; transmitting a power control signal to a terminal according to the comparison result and the set power control variable value; and analyzing the power control signal transmitted to the terminal for a predetermined reference time period and resetting a power control variable. When the subscriber does not move in an area with a favorable radio reception sensitivity (that is, in a state that the Eb/No is a little changed) the base station sets the power control step-size lower than the current step-size and performs a fine power control. Thus, a flux of the transmission power can be prevented. And, since the number of puncturings performed per unit time is reduced, the data transmission efficiency can be heightened.

This paper develops a stochastic geometry-based approach for the modeling and analysis of single- and multi-cluster wireless networks. We first define finite homogeneous Poisson point processes to model the number and locations of the transmitters in a confined region as a single-cluster wireless network. We study the coverage probability for a reference receiver for two strategies; closest-selection, where the receiver is served by the closest transmitter among all transmitters, and uniform-selection, where the serving transmitter is selected randomly with uniform distribution. Second, using Matern cluster processes, we extend our model and analysis to multi-cluster wireless networks. Here, two types of receivers are modeled, namely, closed- and open-access receivers. Closed-access receivers are distributed around the cluster centers of the transmitters according to a symmetric normal distribution and can be served only by the transmitters of their corresponding clusters. Open-access receivers, on the

One of the major challenges in deployed wireless sensor networks (WSN) is to curb down congestion in networks traffic without compromising the energy consumption of the sensor nodes. Congestion disrupts the continuous flow of data, increases loss of information, delays data delivery to the destination and significantly and unnecessarily increases energy consumption in already energy-strapped nodes. Obviously, in healthcare WSN applications, particularly those that cater to medical emergencies or monitor patients in critical conditions, it is desirable to prevent congestion from occurring in the first place. In this work, the authors address the problem of congestion in the nodes of healthcare WSN using a learning automata (LA)-based approach. The primary objective is to adaptively equate the processing rate (data packet arrival rate) in the nodes to the transmitting rate (packet service rate), so that the occurrence of congestion in the nodes can be avoided.
Methods and apparatuses for position determination and other operations. In one embodiment of the present invention, a mobile station uses wireless signals from a plurality of wireless networks (e.g., with different air interfaces and/or operated by different service providers) for position determination (e.g., for data communication, for obtaining time and/or frequency information, for range measurement, for sector or altitude estimation). In one embodiment of the present invention, mobile stations are used to harvest statistical data about wireless access points (e.g., the locations of mobile stations that have received signals from the wireless access points, such as from cellular base stations, wireless local area network access points, repeaters for positioning signals, or other wireless communication transmitters) and to derive location information (e.g., position and coverage area of the wireless access points) for the wireless networks from the collected statistical data.

This dissertation research proposes embedding artificial neural networks into wireless sensor networks in parallel and distributed processing framework to implant intelligence for in-network processing, wireless protocol or application support, and infusion of adaptation capabilities. The goal is to develop in-network intelligent computation and adaptation capability for wireless sensor networks to improve their functionality, utility and survival aspects. The characteristics of wireless sensor networks bring many challenges, such as the ultra large number of sensor nodes, complex dynamics of network operation, changing topology structure, and the most importantly, the limited resources including power, computation, storage, and communication capability. All these require the applications and protocols running on wireless sensor network to be not only energy-efficient, scalable and robust, but also adapt to changing environment or context, and application scope and focus among others, and ...

WBAN device needs a specific function for ubiquitous healthcare application. We propose a scanning algorithm, dynamic discovery and installation, reliable data transmission, device access control, and a healthcare profile for ubiquitous healthcare system.
In the literature, it is common to consider that sensor nodes in a clustered-based event-driven Wireless Sensor Network (WSN) use a Carrier Sense Multiple Access (CSMA) protocol with a fixed transmission probability to control data transmission. However, due to the highly variable environment in these networks, a fixed transmission probability may lead to extra energy consumption. In view of this, three different transmission probability strategies for event-driven WSNs are studied: optimal, fixed and adaptive. As expected, the optimum strategy achieves the best results in terms of energy consumption but its implementation in a practical system is not feasible. The commonly used fixed transmission strategy is the simplest but does not adapt to changes in the systems conditions and achieves the worst performance. In the paper, we find that the adaptive transmission strategy, pretty easy to implement, achieves results very close to the optimal one. The three strategies are analyzed in terms of energy
Data aggregation is an essential operation to reduce energy consumption in large-scale wireless sensor networks (WSNs). A compromised node may forge an aggregation result and mislead base station into trusting a false reading. Efficient and secure aggregation scheme is critical in WSN applications due to the stringent resource constraints. In this paper, we propose a method to build up the representative-based aggregation tree in the WSNs such that the sensing data are aggregated along the route from the leaf cell to the root of the tree. In the cinema of large-scale and high-density sensor nodes, representative-based aggregation tree can reduce the data transmission overhead greatly by directed aggregation and cell-by-cell communications. It also provides security services including the integrity, freshness, and authentication, via detection mechanism in the cells.

MAO YE, CHENGFA LI, GUIHAI CHEN AND JIE WU. Data gathering is a common but critical operation in many applications of wireless sensor networks. Innovative techniques that improve energy efficiency to prolong the network lifetime are highly required. Clustering is an effective topology control approach in wireless sensor networks, which can increase network scalability and lifetime. In this paper, we propose a novel energy efficient clustering scheme (EECS) for single-hop wireless sensor networks, which better suits the periodical data gathering applications. Our approach elects cluster heads with more residual energy in an autonomous manner through local radio communication with no iteration while achieving good cluster head distribution; further more, it introduces a novel distance-based method to balance the load among the cluster heads. Simulation results show that EECS prolongs the network lifetime significantly against the other clustering protocols such as LEACH and HEED.. full text ...

The Red Palm Weevil o Rhynchophorus ferrugineus is an invasive spice that had become a catastrophic plague for lots of palm trees in Saudi Arabia, but all around the world too. Nowadays, the surveillance of the plague is done using tramps placed near the palm trees, and one person comes to the tramp and counts manually the number of weevils into the tramp. This project is aimed to improve the actual surveillance method. To realize it we have been created a Wireless Sensor Network and different nodes able to obtain the number of weevils into the tramp and they must transmit this data to a mobile node that collect all the data for processing. These sensor units are placed into the tramps, so they measure the weight of the weevils, and the number of them. The sensors are Strain Gauges and the signal conditioning system. This signal obtained from the gauges is processed into the Arduino board. To this microcontroller we can add one shield in order to conect communication devices, in our case, Xbees. ...

An on-demand route discovery method in mobile ad hoc networks (MANET) uses simple flooding method, whereas a mobile node blindly rebroadcasts received route request (RREQ) packets until a route to a particular destination is established. Thus, this leads to broadcast storm problem. This paper presents a novel algorithm for broadcasting scheme in wireless ad hoc networks using a fuzzy logic system at each node to determine its capability to broadcast route request packets, based on the node location. Our simulation analysis shows a significant improvement in performance in terms of routing overhead, MAC collisions and end-to-end delay while still achieving a good throughput compared to the traditional AODV.

Non-orthogonal multiple access (NOMA) has become an important principle for the design of radio access techniques for the fifth generation (5G) wireless networks and beyond. Although several 5G multiple access techniques have been proposed by academia and industry, including power-domain NOMA, sparse code multiple access (SCMA), pattern division multiple access (PDMA), low density spreading (LDS), and lattice partition multiple access (LPMA), these techniques are based on the same key concept, where more than one user is served in each orthogonal resource block, e.g., a time slot, a frequency channel, a spreading code, or an orthogonal spatial degree of freedom. Academic and industrial research has also demonstrated that NOMA can effectively support massive connectivity, which is important to ensure that the forthcoming 5G network can support the Internet of Things (IoT) functionalities.Compared to conventional OMA techniques, some new challenges and designs are highlighted by the NOMA technique.

0131]Referring to FIG. 13, as the first device allocates a part of the channel resources allocated from the coordinator, to the second device, it transmits the A/V data to the second device through the other channel resources and receives the A/V data from the second device through the allocated channel resources. Then, the second device can request the first device to increase or decrease the allocated channel resources using the ACK/NACK signal of the A/V data received from the first device. For example, if the second device requests the first device to increase allocation of the channel resources and transmits HRP ACK signal, which includes a data signal of `01` in a TC field, to the first device and the first device accepts the request of the second device, the first device decreases the channel resources used for next A/V data transmission and allocates the other channel resources to the second device. In other words, the available range of the channel resources of the second device ...

Micrwoave Radiation Causes Brain Damage - A study headed by Leif Salford, Department of Neurosurgery at Lund University in Sweden and published in Environmental Health Perspectives shows that cell phone use damages neurons in the brain. This study found that exposure to electromagnetic fields emitted by certain phones was associated with the leakage of labumin through the blood-brain barrier and neuronal damage that increased in response to the amount of exposure. The radiation typically experienced by a user of a cell phone actually burned holes in the brains of rats. The Head Absorbs Radiation - Headaches, nausea, dizziness, short-term memory problems, fatigue, and other complaints resulting from cellular phone use are not due to low-level heating of the brain; instead, theyre apparently caused by the head serving as an antenna and brain tissue as a radio receiver, according to two Jerusalem researchers. Zvi Weinberger, a physicist who heads the applied physics department at the Jerusalem ...
As much as accurate or precise position estimation is always desirable, coarse accuracy due to sensor node localization is often sufficient. For such level of accuracy, Range-free localization techniques are being explored as low cost alternatives to range based localization techniques. To manage cost, few location aware nodes, called anchors are deployed in the wireless sensor environment. It is from these anchors that all other free nodes are expected to estimate their own positions. This paper therefore, takes a look at some of the foremost Range-free localization algorithms, detailing their limitations, with a view to proposing a modified form of Centroid Localization Algorithm called Reach Centroid Localization Algorithm. The algorithm employs a form of anchor nodes position validation mechanism by looking at the consistency in the quality of Received Signal Strength. Each anchor within the vicinity of a free node seeks to validate the actual position or proximity of other anchors within its

Wireless sensor networks (WSNs) and Internet-of-Things (IoT) are among the main enabling technologies for smart systems (transportation, farming, health, etc.). Therefore, WSNs/IoT have received enormous attention where various communications-related performance metrics were considered such as reliability, connectivity, throughput, delay, network life-time, power efficiency, and security. In the literature, WSN design is typically optimized to maximize/minimize one or more of the aforementioned metrics under certain constraints. However, very little work has performed system/network optimization while considering the communications requirements jointly with the decision fusion process. Such approach is expected to produce novel system, network, and signal designs. Consequently, the main objective of this project is to jointly consider communication and data fusion requirements in designing an efficient WSN-IoT system/network that maximizes the control action accuracy and minimizes the system ...

Analog-to-digital converters (ADCs) are crucial blocks which form the interface between the physical world and the digital domain. ADCs are indispensable in numerous applications such as wireless sensor networks (WSNs), wireless/wireline communication receivers and data acquisition systems. To achieve long-term, autonomous operation for WSNs, the nodes are powered by harvesting energy from ambient sources such as solar energy, vibrational energy etc. Since the signal frequencies in these distributed WSNs are often low, ultra-low-power ADCs with low sampling rates are required. The advent of new wireless standards with ever-increasing data rates and bandwidth necessitates ADCs capable of meeting the demands. Wireless standards such as GSM, GPRS, LTE and WLAN require ADCs with several tens of MS/s speed and moderate resolution (8-10 bits). Since these ADCs are incorporated into battery-powered portable devices such as cellphones and tablets, low power consumption for the ADCs is essential.. The ...

Biopharmaceuticals, or treatments such as vaccines and gene, cell, and protein therapies that are derived from biological material, is a growing area of medicine. But producing medicines from materials like living tissue and cells within bioreactors requires careful monitoring.. The wireless sensor capsules, being developed by researchers at the Tyndall National Institute, Cork, and the National Institute for Bioprocessing Research and Training (NIBRT) in Dublin, are designed to move around the bioreactor, monitoring factors that might affect product quality or yield.. Existing sensors, in contrast, are fixed in one position, meaning they can only monitor material that directly passes over them, according to Dr Karen Twomey, staff researcher at Tyndall.. The capsules contain different sensors and associated circuitry, encapsulated in a biocompatible packaging.. In the first generation of the device, which has already been built, an interface circuit connects to the different sensors in the ...
Energy harvesting using piezoelectric material has been one of the hottest interests in powering wireless sensor nodes without maintenance and replacement of wired or battery power system in ubiquitous era. Unlike most of the previous research and applications which have focused on cantilever type of piezoelectric energy converting methods, this research tests 33 mode piezo material which converts relatively vibration of unfixed frequency from ambient vibration into electric energy. To transmit the impact loading to piezo material, we conducted the ball drop experiment. Based on the theoretical model to predict the total stress and voltage influenced by such factors as size of piezo material and mass and velocity of impact material (ball), tests are conducted to earn the optimal estimates of size of PZT and mass and velocity of impact materials for desired energy harvestings concerning its various applications. By altering mass and velocity of impact materials, it is observed to vary voltage
The deployment of the 5G technology(ies) is planned to start by 2020, and these future systems will comprise multiple heterogeneous technologies and services ranging from the personal cellular, wireless local area networks (WLAN) up to the Internet of Things (IoT). The inherent complexity and heterogeneity in technology conjugated with the random nature of both the wireless channel, access and services will make the system evaluation of 5G a very difficult task calling for flexible testbeds where the randomness of the radio environment and mobility can be realistically emulated. In this paper we report the architecture of a flexible and reconfigurable solution currently under deployment in the campus of University of Aveiro, Portugal. The architecture essentially fits the concept of a local cloud-RAN, where remote radio heads (RRH) are deployed within the campus and linked through a front-haul to a central unit located in a laboratory where most of the processing ranging from the PHY layer up to ...
