Mobile Ad-hoc Network (MANET) are formed by a collection of mobile nodes, each equipped with wireless communication capabilities, without relying on any fixed infrastructure. In order to maintain network connectivity, each node may act as an ad hoc router, forwarding data packets for other mobile nodes that may not be within direct transmission range of each other. Energy efficiency is a most important design consideration in MANET due to the limited battery life of mobile terminals. The network lifetime will be improved by suitably reducing the requirement of power for connections. The objective of this paper is to develop a new routing protocol for MANET. I proposed the enhanced version of Power Aware Optimized Link State Routing (PA-OLSR) protocol using proactive OLSR protocol. This proposed PA-OLSR routing protocol uses a new metric to find the route with higher transmission rate, less latency and better stability. It checks bandwidth and delay constraint during route request and uses as well new mobility prediction mechanism to determine the stability of link during a path selection. We evaluate the performance of PA-OLSR using NS2 simulation tool and compare it with OLSR protocol. The simulation results show that the performance of new routing protocol significantly improves the network performance by discovering the required path with minimal power and delay.
