Group communications are important in Mobile Ad-hoc NETworks (MANETs). Multicast is a resourceful method for implementing group infrastructure. However, it is testing to implement efficient and scalable multicast in MANET due to the complexity in group attachment management and multicast packet forwarding over a active topology. The authors propose a story Efficient Geographic Multicast Protocol (EGMP). EGMP uses a virtual-zone-based arrangement to implement scalable and well-organized group membership organization. A net workwide zone-based bidirectional tree is constructed to achieve more well-organized membership management and multicast delivery.
