Enhancement in Divide and Conquer Scheme with Relay Nodes to Solve the Energy Hole Problem in WSN

Abstract

In wireless sensor network, sensor nodes have the limited battery power, so in order to utilize the energy in a more efficient way several author’s developed some techniques, but still there is need to reduce the energy consumption of nodes. In this paper, we introduced a new technique called as ‘Divide and Rule technique’ to solve the coverage hole by dividing the network field into subfield and next avoid the energy hole problem with the help of static clustering. Basically, in divide and rule scheme network area is divided into three regions namely inner, middle and outer to overcome the problem of energy consumption. We implement this work in NS-2 and our simulation results show that our technique is far better than old techniques.
