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...
Multicast transmission, wherein the same packet must be delivered to multiple receivers, is an important aspect of sensor and tactical networks and has several distinctive traits ...
We consider a high density of sensors randomly placed in a geographical area for event monitoring. The monitoring regions of the sensors may have significant overlap, and a subset...
