ABSTRACT
Wireless sensor networks (WSN) are emerging in various fields like disaster management, battle fieldsurveillance and border security surveillance. A large number of sensors in these applications areunattended and work autonomously. Clustering is a key technique to improve the network lifetime, reducethe energy consumption and increase the scalability of the sensor network. In this paper, we study theimpact of heterogeneity of the nodes to the performance of WSN. This paper surveys the different clusteringalgorithm for heterogeneous WSN.
