Mobile Ad-hoc Network (MANET) is an emerging area of research in the communication network world. MANET is a group of wireless mobile nodes dynamically establishing a short lived network without any use of network infrastructure or centralized administration. In addition to the high degree of mobility, MANET nodes are distinguished by their limited resources such as power, bandwidth, processing, and memory. In this paper, the authors modified proactive Optimized Link State Routing (OLSR) Protocol for MANET through the proposed new routing algorithm named Energy Saver Path Routing (ESPR) algorithm and the evaluation of this routing algorithm is compared with ordinary OLSR protocol through experiments and simulations. This proposed ESPR algorithm takes minimum energy to find the path between source and destination through edge node calculation. This edge node calculation is executed based on the highest potential score node selection towards destination with sufficient forward capacity. This ESPR algorithm provide better performance than ordinary OLSR and also improved packet delivery ratio, reduced end-to-end delay and reduced transmission power to transfer the packet from source to destination.
