DECP: A distributed election clustering protocol for heterogeneous wireless sensor networks

Abstract

Heterogeneous wireless sensor networks are energy limited and imbalance networks, load balancing and energy efficiency is the most challenging task in these networks. In this paper, we propose a distributed election clustering protocol to prolong the stable region of wireless sensor networks, which is based on remaining energy and communication cost to elect suitable cluster-head nodes. Compared with classical clustering protocol, our protocol can maintain load balancing of networks, and extremely prolong the stable region of network lifetime. © Springer-Verlag Berlin Heidelberg 2007.
