Now-a-day's group communications are important in Mobile Ad-hoc NETworks. Efficient method for implementing group communications is multicasting. But, due to difficulty in group membership management and multicast packet forwarding over a dynamic topology it is a challenge to implement efficient and scalable multicast with security in MANET. The authors propose a novel Secure Efficient Geographic Multicast Protocol (SEGMP) by modifying existing EGMP. SEGMP uses a virtual zone based structure to implement efficient and scalable group membership management scheme.
