In MANET group communication is an important characteristic which can be implemented through Multicasting. MANET has a dynamic topology through which the mobile nodes keep changing their location and thus it doesn't have a fixed infrastructure, this makes forwarding and membership a tedious work. EGMP (Efficient Geographic Multicast Protocol) is a virtual-zone-based structure that is used to implement the efficient group membership management. The zone honcho takes the responsibilities of all the nodes up-to-date information and when there is a data loss to a particular crashed node it buffers the data packet and sends the packets when the respective node has been recovered.
