A wireless sensor network consists of many low-cost, low-power sensor nodes to perform sensing environment and transmitting sensed information to a base station. Energy efficient is a main design factor for wireless sensor network. It is a significative method to prolong the lifetime of sensor network through deploying some relay nodes. In this paper, we present an approximate algorithm for the relay...
Clustering is an efficient and important method to facilitate energy conservation. Aiming to alleviate the high overheads of migrating management information in the re-clustering process of a clustering algorithm, an energy efficient, Complete Graph-based Clustering Algorithm (CGCA) is proposed in a densely deployed sensor network. CGCA divides the network into a few complete graphs, each complete...
