—Conventional 802.11 medium access control (MAC) characteristics. In particular, all of these designs adopted a protocols have been designed separately from the characteristics s...
Duty cycling is often used to reduce the energy consumption caused by idle listening in Wireless Sensor Networks (WSNs). Most studies on WSN protocols define a common duty cycle va...
—WiMAX is one of the most promising emerging broadband wireless technologies. As a consequence, data transfer performance optimization represents a crucial issue due to TCP limit...
Wireless 802.11 hotspots have grown in an uncoordinated fashion with highly variable deployment densities. Such uncoordinated deployments, coupled with the difficulty of implemen...
This paper describes the design, implementation and evaluation of a search and rescue system called CenWits. CenWits uses several small, commonly-available RF-based sensors, and a...
