In this paper, I propose a new energy efficient clustering scheme to prolong the networklifetime by reducing energy consumption at the sensor node. It is possible that a nodedetermines whether to participate in clustering with certain probability based on localdensity. This scheme is useful under the environment that sensor nodes are deployedunevenly within the sensing area. By adjusting the probability of participating in clusteringdynamically with local density of nodes, the energy consumption of the network is reduced. So, the lifetime of the network is extended. In the region where nodes are densely deployed,it is possible to reduce the energy consumption of the network by limiting the number ofnode which is participated in clustering with probability which can be adjusted dynamicallybased on local density of the node. Through computer simulation, it is verified that the proposed scheme is more energyefficient than LEACH protocol under the environment where node are densely located in aspecific area.
