A Survey on Cluster Head Selection Techniques

Monika, Pooja Ahlawat

Abstract: Low energy adaptive Hierarchical clustering Protocol (LEACH) is used to transfer the data to sink node by utilizing minimum amount of energy. It forms clusters of nodes that can adapt according to the various parameters like energy etc. TO enhance the network lifetime various modifications are proposed to the LEACH. These modifications include different procedures to form clusters and to select cluster head. This paper compares LEACH and its various enhancements. This paper also describes the active and the passive clustering.
