MASEHA: Multi-hop Communication Using Active and Sleep Nodes for Energy Hole Avoidance in Wireless Sensor Networks

Energy Hole is the major problem in the efficiency of Wireless Sensor Networks (WSNs). A routing protocol MASEHA: Multi-hop communication using Active and Sleep nodes for Energy Hole Avoidance is proposed in this research paper to overcome the energy hole problem. Taking the concept of Active and sleep mode of nodes, we propose that the network is divided into active and sleep nodes. Half of the sleep nodes are turned on when the first node dies and remaining sleep nodes are activated after the death of tenth node. We have achieved balanced stability, increased sensing period of nodes and balanced energy consumption. Further, MASEHA uses dynamic clustering, divides the network into small sub-areas and uses uniform number of CHs throughout the network. Selection of CHs is done on the basis of maximum energy and minimum distance multi-hop communication is utilized in our paper. Simulation results show that these aspects help in out performing our proposed protocol with the existing protocols.
