Deterministic multicast link based energy optimized routing in MANET

Abstract

An energy efficient routing plays a significant role in Mobile Ad-hoc Networks (MANETs). Probabilistic routing method is designed for MANETs to selects the best path in a network while transmitting the packets and to reduce the average energy per packet. However, in probabilistic routing, the packets which are sent fail to reach the exact destination so it requires rebroadcasting which resulting in higher energy consumption. In order to overcome such limitations, an effective routing mechanism called Deterministic Multicast Link Based Energy Optimized Routing (DML-EOR) is proposed to select the optimized route path for efficient data packet transmission in MANETs. Initially, DML-EOR mechanism performs Deterministic Link Stability Estimation to search possible stable routes from the source to destination in order to enhance the Packet Delivery Ratio (PDR) and to reduce the average End to End Delay (EED). After that, DML-EOR mechanism computes Link Reliability criterion to select optimized route path among all available paths with minimum residual energy. Finally, DML-EOR mechanism performs effective data transmission through the selected optimized route path which results in improved Network Lifetime (NL) and minimum Energy Consumption (EC). The performance of DML-EOR mechanism is measured in terms of Energy utilization (EU), NL, PDR and average EED. The simulations result shows that the DML-EOR mechanism is able to improve the PDR by 9% and also reduces the EC of routing process by 30% when compared to state-of-the-art-works.
