摘要:Wireless sensor networks (WSNs) is a collection of large number of tiny, limited battery powered sensor nodes. Minimizing energy consumption and maximizing network lifetime are the primary goals when designing applications and protocol for WSNs. Clustering sensor nodes proven to be an effective and energy efficient way to extend the lifetime of wireless sensor networks. One of the major challenging issues of a clustering protocol is selecting an optimal group of sensor nodes as cluster head (CH) to partition the network. In this paper, an Energy Balanced Fixed Clustering (EBFC) protocol is proposed and evaluated. The protocol creates a fixed number of clusters and maintained throughout the lifetime. Energy load have been distributed evenly among all the nodes by rotating the role of cluster heads. In EBFC protocol, cluster heads and next heads have been selected based on the residual energy and location of the nodes in advance. The results show that EBFC significantly increases the lifetime.
