摘要：Cluster interactions are imperative in Mobile Ad hoc Networks (MANET). Multicast is an proficient technique for implementing cluster connections. However, it is exigent to execute competent and scalable multicast in MANET due to the intricacy in faction association supervision and multicast packet forwarding over a dynamic topology. We intend a novel Efficient Geographic Multicast Protocol (EGMP). EGMP uses a virtual- zone-based formation to execute scalable and proficient group membership supervision. A network-wide zone-based bi- directional tree is constructed to accomplish extra proficient association supervision and multicast deliverance. The situation information is used to steer the zone configuration edifice, multicast tree creation and multicast packet forwarding, which proficiently reduces the overhead for direction incisive and tree configuration maintenance. Several strategies have been anticipated to promote develop the efficiency of the protocol, for example, introducing the theory of zone intensity for edifice an optimal tree formation and integrating the position search of cluster members with the hierarchical group membership executive. Finally, we intend a scheme to lever vacant zone dilemma faced by most routing protocols using a zone constitution. The scalability and the efficiency of EGMP are evaluated through simulations and quantitative investigation. Our imitation results express that EGMP has high envelope liberation ratio, and low manage transparency and multicast group amalgamation hindrance under all test scenarios, and is scalable to both group size and network size. Compared to Scalable Position-Based Multicast (SPBM) [20], EGMP has appreciably lower control overhead, data transmission overhead, and multicast group unification delay.
