Modified local link failure recovery multicast routing protocol for MANET

Abstract

Multicasting in mobile ad hoc networks (MANETs) is a technique to transfer data to the group of destinations from single or group of source nodes. However, the devices in the MANETs move randomly in the network leading to regular modify the topology. The link breakages occurring due to constant changing topology reduce the performance of the network. This paper presents a multicasting routing protocol that focuses on repairing the local links in an energy efficient way. The proposed Modified Local Link Repair (MLLR) multicasting routing protocol rebuilds the link from the uplink node to the node next to the downlink node. The performance of the procedure has been compared based on throughput, packet delivery ratio and remaining energy of the network. The proposed procedure has shown improvement over the existing EOD-LLR multicasting routing protocol.
