Using directional antennas in wireless ad hoc networks can significantly improve network performance. However, the deafness problem greatly limits the network performance. This pa...
The in-network query processing paradigm in sensor networks postulates that a query is routed among sensors and collects the answers from the sensors on its trajectory. It works f...
An important problem in mobile ad-hoc wireless sensor networks is the localization of individual nodes, i.e., each node’s awareness of its position relative to the network. In t...
In this paper, we study the fundamental limits of a wireless sensor network's lifetime under connectivity and k-coverage constraints. We consider a wireless sensor network wit...
Wireless sensor networks offer the potential to span and monitor large geographical areas inexpensively. Sensors, however, have significant power constraint (battery life), makin...
