Abstract : This research aimed at creating robust and efficient operation in mobile ad-hoc networks (MANETs) by incorporating energy efficient routing technique. MANETs are energy constrained. The Energy Skilled Ad-hoc on Demand Distance Vector (ESAODV) with Priority-Based Weighted Fair Queue (PBWFQ) routing scheme was developed and compared with Destination-Sequenced Distance-Vector (DSDV) with First-In-First-Out (FIFO) routing techniques using NS-3 (Network-simulator). WireShark Network Analyzer was used for file tracing and analysis of the simulation results in NS-3. The optimized technique significantly reduced the control traffic and packets congestions by lowering the end-to-end delay to an average of 25 X 10-3 s in a 50-100 nodes MANET. ESAODV-with-PBWFQ maintained throughput of 78.8 X 103 pps. The technique met target Packet Delivery Ratio with 98.7% accuracy. ESAODV-with-PBWFQ saved 80-90% energy compared to DSDV-with-FIFO in 80-100 nodes dense MANET. In 50-70 nodes sparse MANET 70-75% less consumption of energy in ESAODV-with-PBWFQ compared to DSDV-with- FIFO.
