Abstract

In wireless sensor networks the minimization of energy dissipation is a major concern. In order to increase the network lifetime sensor nodes are grouped into clusters and a cluster head (CH) is selected. This process of cluster head selection and setting up of clusters can be done in two ways - Distributed & Centralized. LEACH is a distributed clustering protocol which reduced the energy consumption upto a great extent. After that a centralized clustering approach was introduced(C-LEACH). Centralized clustering involves the selection of cluster heads by the base station itself. It is done on the basis of amount of residual energy and distance of sensor node from BS. In this paper we study and compare both these clustering approaches.
