Mobile Energy Efficient Selective Opportunistic Routing for Mobile Wireless Sensor Networks

When Wireless Sensor Networks (WSN) is considered the energy consumption becomes the major issue. Since the sensor nodes are deployed in a rough terrain with unpredictable environmental conditions the nodes may fail due to battery drain and at many situations the batteries cannot be replaced. When Mobile Wireless Sensor Networks (MWSN) are considered the energy consumption becomes a critical issue. It would be wise to minimize the energy consumption by using a better routing algorithm so that a quality path can be selected. One such routing protocol is Opportunistic routing in this type of routing for each packet the next relay node is selected dynamically, Specifically this paper deals with an opportunistic routing algorithm called Mobile Energy Efficient Selective Opportunistic Routing (MEESOR) that reduces the size of the forwarder list by including the neighbors that are nearer to the destination .The selection of the relay node depends the nodes distance from the destination and the residual energy. The routing of the acknowledgement also takes place in an opportunistic manner as the data packet so that the energy consumption gets balanced. The Route Failure Notification provides a better indication to select a new route. The algorithm provides better results than the existing opportunistic routing algorithms in terms of End-to-End delay, and network life time.
