In Mobile Multi-hop Relay (MMR) networks, Relay Multicast Rekeying Algorithm (RMRA) is meant to ensure secure multicast communication and selective updating of keys in MMR networks. However, in RMRA, the rekeying is carried out after a specific interval of time, which cannot ensure the security for multicast communication on joining the member. Secondly, the rekeying scheme generates a huge communication overhead on the serving Multi-hop Relay Base Station (MR-BS) on frequent joining of members. Lastly, there is nothing about when a member left the group communication.
