End system multicast protocols have the advantage thatnon-member nodes are not burdened with multicast routingand storing state information. Unfortunately, most existingend system multicast protocols are developed for the traditionalInternet. This paper shows how these protocols canalso be utilized in mobile ad-hoc networks (MANET). Toachieve this the protocols have to be adapted to fit the highlydynamic network topology, link failures and other particularitiesof MANETs. The paper shows how the existingNICE protocol can be improved to operate more efficientin such an environment. This is achieved by exploiting thebroadcast capabilities of the medium, permanent adaptationto the dynamic network topology and a distance metricthat is based on hop count instead of latency measurements.Simulations show that the proposed improvements greatlyincrease the efficiency of the protocol in MANETs. Moreover,the proposed protocol introduces the Local BroadcastCluster concept that exploits the broadcast medium betterthan any other existing overlay approach.
