A Novel Energy Efficient Routing Algorithm for Wireless Sensor Networks Using Sink Mobility

Abstract

There are numerous applications for wireless sensor networks which are inevitable now a day in our daily life. Majority of such applications which use wireless sensor networks will be in areas where the direct human intervention is impossible. So the limited energy available in such sensors is a threat for prolonging the life of the entire network. The need of energy efficiency in wireless sensor networks is a hot research topic in which lot of new strategies for improvement in energy efficiency has been sought after. As communication process consumes more energy, an energy efficient routing strategy can probably reduce the energy consumption to a great extend. This paper gives an overview of the different routing techniques in which mobile sinks are used to facilitate the routing process which can effectively reduce the energy use. A new routing strategy with mobile sinks and a static sink is proposed and is compared based on the matrices life time and average energy of the nodes with the existing Shortest Hop path (SH) algorithm. The simulation results shows the proposed algorithm is more energy efficient than the existing one.
