Abstract

In mobile ad hoc networks, an application scenario requires mostly group mobility behavior in the mix of group moving nodes and individually moving nodes. The nodes of those applications tend to belong to the movement group with similar movement behavior. Group mobility is one of the good methods to improve scalability, and reduces the protocol overhead. In this paper, we propose the multicastarchitecture which regards nodes that have equal group mobility in the heterogeneous group mobility network as the single entity with the multiple interfaces and composes multicast tree. The logical cooperative entity-based multicast architecture accommodates the scalability,the multicast tree simplification, and the protocol overhead reduction which are obtained from the hierarchical multicast architecture, while it maintains the flat multicast architecture for the data transmission. It also prevents the concentration of the energy consumptiondispersing data forwarding load into the several ingress/egress nodes. Results obtained through simulations show that logical entity-based multicast protocol with multiple interfaces offers the protocol scalability and the efficient data transmission.
