LORD: A Localized, Reactive and Distributed Protocol for Node Scheduling in Wireless Sensor Networks
13 years 7 months ago
The lifetime of wireless sensor networks can be increased by minimizing the number of active nodes that provide complete coverage, while switching off the rest. In this paper, we ...
