Surveillance has been a typical application of wireless sensor networks. To conduct surveillance of a given area in real life, one can use stationary watch towers, or can also use...
Energy efficiency is a critical issue in designing sensor networks, as the nodes have limited battery power. In this paper we propose to move the BS so as to prolong the network l...
recently, mobile agents have been used to solve many problems in wireless sensor networks. Agents are usually transferred from a node to another to aggregate the sensed data and si...
The wireless sensor network based localization system—Cicada is designed to support the locationawareness in indoor environment. The system is based on TDOA (time difference of ...
—In a broadcasting task, source node wants to send the same message to all the other nodes in the network. Existing solutions range from connected dominating set (CDS) based for ...
