POMA: Prioritized Overlay Multicast in Ad Hoc Environments

Abstract: Overlay Multicast networks in mobile ad-hoc environments have received much attention due to their increasing number of practical applications. Although overlay multicast is not as efficient as IP-based multicast, they have the advantages of being easy to implement and flexible to adapt. In many applications, some participating nodes might be members of more than one overlay trees or may wish to build a temporary tree in order to perform certain important tasks. The priority of these trees can be defined by the importance of the service. For the success of such an application, it is necessary that nodes belonging to more than one tree are smart enough to ignore incoming messages from members in low priority trees while they are listening to members from a higher priority tree. In this paper, we present a prioritized overlay multicast in ad-hoc environments (POMA). POMA builds priority trees with certain nodes carrying important tasks in overlay networks, and rearranges low pr...
