Power Efficient Routing Protocol for Mobile Ad Hoc Networks

Mobile Ad hoc Networks (MANETs) routing is challenged by power and bandwidth constraints as well as frequent topology changes due to which it must adapt to and converse quickly. The absence of any central coordinator and infrastructure less network make routing a complex one for MANETs. Routing protocols consider the path with the minimum number of hop counts as the efficient path for transmission of data packets to any given destination. However, it does not provide efficient power consumption and may create node failure resulting loss of data packets. If the battery of a node is drained out, then it cannot communicate with other nodes and the number of dead nodes makes the network partition. A routing protocol called Power Efficient Routing (PER) is proposed which enhances the quality of services ’ issues such as Packet Delivery Ratio, End to End delay, Energy Consumption and Network Lifetime. This paper presents a scheme for efficient power routing based on residual battery capacity, transmission power, and hop count to route the data packets. A simulation study demonstrates the effectiveness of proposed scheme to provide reliable transmission than the existing AODV.
