Residual Energy Extraction Using Centralized Scheduling Algorithm

Wireless sensor networks consist of small size, low cost, low power sensor nodes. Due to its limited power source, energy consumption has been concerned as the most critical factor when designing sensor network protocols. Facing this challenge, several approaches to prolong lifetime of the sensor networks, including scheduling where active nodes provide essential k-coverage have been investigated. Here we use centralized scheduling scheme in which the base station determines and issues the scheduling decisions. To extend the network lifetime and to extract the useful energy further from the network, we go for compromise in the area covered by nodes.
