We study the utility of dynamic frequency agility in realworld wireless sensor networks. Many view such agility as essential to obtaining adequate reliability in industrial enviro...
Traditional wireless broadcast protocols rely heavily on the 802.11-based CSMA/CA model, which avoids interference and collision by conservatively scheduling transmissions. While C...
The IEEE 802.15.4 specification outlines a new class of wireless radios and protocols targeted at low power devices, personal area networks, and sensor nodes. The specification ...
Protocols designed to provide error-free communications over lossy links, at both data link and transport layers, commonly employ the idea of sliding windows, which is based on th...
Overlay Networks (ONs) are logical networks built on top of a physical network with the aim of moving part of the routing complexity to the application layer. At the same time, sen...
