Abstract: Wireless Sensor networks, a huge number of small sensors are deployed to create a network which cooperate together to set up a sensing network. To develop applications and protocols for sensor network, the maximum network lifetime and minimal energy consumption should be considered as important parameters. Improved network lifetime, scalability and load balancing are important parameters for wireless sensor networks. Clustering is very useful technique through which we can affect these factors. The method of clustering prolongs network topology by using energy, bunch and centrality factors and also the distances between nodes for formulating clusters. A supervisor node is assumed which elects new cluster head when existing cluster head fails. This property causes a raise in network lifetime. This survey compares the performance of distributed energy-aware clustering algorithm such as LEACH, FEED, HEED, EADC protocol. The report is based on energy consumption, network lifetime and scalability from the previous works that has been done.
