Wireless sensor networks are small, inexpensive and flexible computational platforms, that have found popular applications in various areas including environmental monitoring, he...
— Before a sensor network is deployed, it is important to determine how many sensors are required to achieve a certain coverage degree. The number of sensor required for maintain...
— Lifetime maximization is one key element in the design of sensor-network-based surveillance applications. We propose a protocol for node sleep scheduling that guarantees a boun...
