Abstract

This Technological development of micro-electronics and wireless networks have created a new generation of large scale sensor suitable for a varied range of applications, it is the wireless sensor networks (WSN). In spite of the remarkable advances in WSN, there are still many problems to solve. However, the control of the energy consumption by sensor networks and maximizing their lifetime are the most fundamental issues. The use of wireless sensor networks is often correlated with an absence of infrastructure this raises the problem of activation of the network topology and maintaining this connectivity. Therefore the network needs to perform an initialization phase to self-organize. Actually most of self-organization protocols used in wireless sensor networks is mainly based on clustering. In this paper, we present a survey of clustering algorithms based on energy efficiency in WSNs highlighting their objectives, features, complexity, etc.
