摘要：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. We enhance the data delivery by keeping the data more secure through some encryption technique. Finally, we try to encrypt the data through a PGP framework and so that the intermediates' cannot view the message. Thus the data loss has been decreased and it enhances the packet delivery ratio (PDR).
