摘要：Mobile Ad Hoc Networks (MANETs) are a set of mobile nodes collected in groups with no fixed infrastructure and self organized. MANETs suffers from many limitations such as scarce resources and unexpected dynamic architectural which makes finding the most stable route to transmit data packets a challenging task. Multicasting is designed to improve the group oriented applications. Several studies proposed multicast routing protocols in MANETs, most of which still lack route stability. In this paper we propose a new algorithm, Long Lifetime Multicast Routing Protocol (LLMRP), based on On-Demand Multicast Routing Protocol (ODMRP). The proposed algorithm modifies the route discovery process and data packets multicasting in original ODMRP to discover the most stable route. The main goal of our proposed mechanism is to increase the route lifetime and reduce the need for route maintenance mechanism, to decrease the control overhead and average end-to-end delay.
