IMPROVING AVERAGE ENERGY COVERAGE IN HETEROGENEOUS NETWORK USING FARTHEST NODE SEP PROTOCOL IN WSN

The impact of heterogeneity nodes, in terms of their energy, in wireless sensor networks that are hierarchically clustered. We show that the behavior of such sensor networks becomes very unstable once the first node dies, especially in the presence of node heterogeneity. A new dynamic strategy for selecting the optimal cluster head in Stable Election Protocol (SEP). The proposed strategy selects a node as cluster head if it has the maximum energy among all the available nodes in that particular cluster. The maximum energy is that which is calculated at running time of the WSN. The proposed strategy considers heterogeneous farthest distance based nodes and divides nodes among normal, intermediate and advance nodes which improving the average energy consumption with farthest distance base node using MATLAB tool.
