We propose an architecture for supporting geomulticast services with high message delivery ratio in mobile ad-hoc networks. Since in ad hoc networks there is no fixed infrastructure as in cellular networks, we use mobility based clustering to cluster the various mobile nodes. We describe several geomulticast zone formulation and representation methods that present trade offs between accuracy, simplicity and cost effectiveness. Moreover we propose a direction guided routing (DGR) protocol which creates a cluster-head based limited mesh structure within a guided region, in order to deliver packets with reliability and reduced overhead to the final destinations. Finally the performance evaluation of the proposed architecture is achieved via modeling and simulation.
