Topology Control in Wireless Ad Hoc and Sensor Networks makes the case for topology control and provides an exhaustive coverage of TC techniques in wireless ad hoc and sensor networks, considering both stationary networks, to which most of the existing solutions are tailored, and mobile networks. The author introduces a new taxonomy of topology control and gives a full explication of the applications and challenges of this important topic.
Wireless Sensor Networks hold the promise of delivering a smart communication
paradigm which enables setting up an intelligent network capable of handling
applications that evolve from user requirements. With the recent technological
advances of wireless sensor network, it is becoming an integral part of our lives.
However, due to the nature of wireless sensor networks, researchers face new
challenges related to the design of algorithms and protocols.
Wireless Sensor Networks (WSNs) can be defined as a self-configured and infrastructure-less wireless networks to monitor physical or environmental conditions, such as
temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass
their data through the network to a main location or sink where the data can be observed
and analysed. A sink or base station acts likean interface between users and the network.
One can retrieve required information from the network by injecting queries and gathering
results from the sink.
This book provides the basics needed to develop sensor network software and supplements it with many case studies covering network applications. It also examines how to develop onboard applications on individual sensors, how to interconnect these sensors, and how to form networks of sensors, although the major aim of this book is to provide foundational principles of developing sensor networking software and critically examine sensor network applications.
This book guides readers through the basics of rapidly emerging networks to more advanced concepts and future expectations of Telecommunications Networks. It identifies and examines the most pressing research issues in Telecommunications and it contains chapters written by leading researchers, academics and industry professionals. Telecommunications Networks - Current Status and Future Trends covers surveys of recent publications that investigate key areas of interest such as: IMS, eTOM, 3G/4G, optimization problems, modeling, simulation, quality of service, etc.

Insider attacks pose an often neglected threat scenario when
devising security mechanisms for emerging wireless technologies.
For example, traffic safety applications in vehicular
networks aim to prevent fatal collisions and preemptively
warn drivers of hazards along their path, thus preserving
numerous lives. Unmitigated attacks upon these networks
stand to severely jeopardize their adoption and limit the
scope of their deployment.
Turn your iPhone or iPad into the hub of a distributed sensor network with the help of an Arduino microcontroller. With this concise guide, you’ll learn how to connect an external sensor to an iOS device and have them talk to each other through Arduino. You’ll also build an iOS application that will parse the sensor values it receives and plot the resulting measurements, all in real-time.
Wireless sensor nodes are small, embedded computing devices that interface with sensors/
actuators and communicate using short-range wireless transmitters. Such nodes act
autonomously, but cooperatively to form a logical network, in which data packets are routed
hop-by-hop towards management nodes, typically called sinks or base stations. A Wireless
Sensor Network (WSN) comprises of a potentially large set of nodes that may be distributed
over a wide geographical area, indoor or outdoor
Over the past decade, there has been a prolific increase in the research, development
and commercialisation of Wireless Sensor Networks (WSNs) and their associated technologies
(see Figure 1). This rise has been a result of a number of contributing factors,
including continued miniaturisation (leading towards an era of truly ‘pervasive’ and
‘invisible’ computing); low-power circuits, devices and computation (for example, the
ultra-low-power sleep states now found in microcontrollers); and efficient short-range
communication (such as ZigBee and Bluetooth).
We live in an era of unimaginably rapidly advancing and amazing technologies that enable instantaneous flow of information – anytime, anywhere. The convergence of computers and networks has been the key force behind the development of these awesome technologies. Increasing use of systems..
Wireless Sensor Networking is one of the most important new technologies of the
century and has been identified to see significant grow in the next decades. Wireless
sensor networks are power-efficient, small-size and communicate wirelessly among each
other to cooperatively monitor and access the properties of their targeted environments.
Applications reach from health monitoring, through industrial and environmental
monitoring to safety applications.
Wireless Sensor Networks came into prominence around the start of this millennium
motivated by the omnipresent scenario of small-sized sensors with limited power deployed
in large numbers over an area to monitor different phenomenon. The sole motivation
of a large portion of research efforts has been to maximize the lifetime of the
network, where network lifetime is typically measured from the instant of deployment
to the point when one of the nodes has expended its limited power source and becomes
in-operational – commonly referred as first node failure....
Accurate determination of the mobile position constitutes the basis of many new applications. This book provides a detailed account of wireless systems for positioning, signal processing, radio localization techniques (Time Difference Of Arrival), performances evaluation, and localization applications. The first section is dedicated to Satellite systems for positioning like GPS, GNSS. The second section addresses the localization applications using the wireless sensor networks.
