An Energy Efficient Mobile Sink Path Selection And Routing Algorithm For WSN

Wireless Sensor Network (WSN) is a collection of sensor nodes. A sensor node covers all information which is present in its sensing range. To access the information present in some other sensor range, the networks use a process called Routing. One of the routing problems in wireless sensor network (WSN) is concerned with maximizing the sensor network lifetime while continuously routing the collected data (information) to the base station (central server). A route (sometimes called as Path) is a set of sensors that establish a connection between a source node and a sink node (base station). The routing is used to determine a set of different routes with maximum aggregated lifetime while constraining the life of each sensor by its initial battery life. In WSN, we demand an energy-efficient path which is used to send collected information to the center base station. At the base station, the received data are processed further. Recent advances in wireless sensor networks have led to many new protocols specifically designed for sensor networks where energy awareness is an essential consideration. An energy efficient method for energy balanced routing for WSN is proposed in this paper. In this method, the next-hop node is selected according to the awareness of link weight and forward energy density. The efficiency of proposed energy aware routing method is proved through MATLAB simulation results.
