Abstract

The aim of this study is to reduce the number of link failures and provide a quick recovery mechanism in MANETs. Multicasting is one of the greatest issues among MANETs due to the seamless variations in topology and link dynamics. Due to the wireless nature of the network, the nodes are under the compulsion to perform communication at adverse situations for any emergency or defense operations. The On Demand Multicast Routing Protocol (ODMRP) is one of the solutions proposed to avoid the multicasting problem in Wireless Mobile Ad hoc Network. In order to avoid excessive flooding of control messages in the network, Enhanced ODMRP was proposed that introduced short time frames to wait until the refresh messages are flooded. In this study, we propose a quick recovery mechanism that along with the EODMRP helps in the quick recovery from route failures and increases performance in the network. An analysis of the EODMRP protocol for multicasting in MANETs is presented along with the proposed quick recovery mechanism using simulations in the network simulator.
