Abstract: In a mobile ad hoc network, nodes are often powered by batteries. The power level of a battery is finite and limits the lifetime of a node. Every message sent and every computation performed drains the battery. One solution for power conservation in mobile ad hoc network is power awareness routing. This means that routing decisions made by the routing protocol should be based on the power-status of the nodes. Nodes with low batteries will be less preferably for forwarding packets than nodes with full batteries, thus increasing the life of the nodes. A routing protocol should try to minimize control traffic, such as periodic update messages to improve the lifetime of the nodes and network. However, not every routing protocol is suitable for implementing power awareness routing and different approaches on power awareness routing. In this paper we present Power Awareness Routing in OSPFV2 and RIPV2 protocols using QualNet 5.0 simulator. Two different IGP based routing protocols are used for generating Link State Updates in OSPFV2 and distance vector RIPV2 routing prototype. For effective performance of these routing protocols we also analyzed their comparison on the basis of measuring metrics like Average jitter, Average end to end delay, Packet Delivery ratio, Power consumed (mw) in transmit, received and ideal modes, using random mobility model, varying CBR traffic load and number of nodes can be used to create practical networks that emulate real network scenarios.
