摘要：Wireless sensor networks (WSNs) have gained increasing importance in a variety of military and civilian applications. The most important issue faced in all wireless sensor networks is its energy consumption. Innovative techniques that improve energy efficiency to prolong the network lifetime are highly required. Clustering is an effective topology control approach in wireless sensor networks, which can increase network scalability and lifetime. In this paper, we propose a novel energy efficient clustering approach (E2C) for single-hop wireless sensor networks, which better suits the periodical data gathering applications. E2C is a clustering technique in which the network is partitioned into a group of cluster regions with one cluster head in each cluster region.E2C uses a new method of election of cluster heads and clusters formation. The finest value of competition range produces a good distribution of cluster heads. Further in the cluster formation phase, plain nodes join clusters not only taking into account its intra-cluster communication cost, but also considering cluster heads cost of communication to the BS. Simulation results show that E2C prolongs the network lifetime significantly against the other clustering protocols such as LEACH, HEED and EECS.
