Low-power, short-range, low-data-rate wireless networks use the unlicensed RF band. In addition to their overriding need to operate on severely constrained energy sources, such as using one battery ...

This article has presented OAGF, a robust and energy-efficient geographic routing protocol for wireless sensor networks (WSNs ...

Environmental monitoring depends on distributed monitoring solutions to cover areas that, in most cases, don’t require ...

Last week, roving reporter John Cox took a trip into the experimental world of wireless sensors. This is an area that’s “pre-standard,” as they say, but when you start to consider the possibilities, ...

Industries everywhere are finding ways to save not only on energy and its costs but through the use of wireless networks and in numerous other ways too. According to Oak Ridge National Laboratories, ...

When first responders arrive at a major incident such as a fire, they must first determine the extent of the hazard. Networks of remote sensors are ideal for this purpose since they can provide ...

Key predistribution schemes (KPSs) have emerged as a central strategy to secure wireless sensor networks, where the constraints of limited memory, processing power and energy demand lightweight yet ...

The global market for wireless sensor network (WSN) systems and services is expected to skyrocket to about $4.6 billion in 2011, up from approximately $500 million today, according to a recent report ...

The use of wireless sensors in wellhead monitoring of oil and gas fields is a key application that shows promise. The measurements involved are conventional process measurements of pressure, level and ...

You'd have to be blind and deaf not to have noticed the excitement overpeer-to-peer (P2P)networking, particularly at venues such as last week's SensorExpo. For a long time P2P was predominantly used ...
