EVALUATE THE ZONE BASED ROUTING PROTOCOL WITH STATELESS MULTICASTING FOR MANET
Panchamy Krishnakumari, E. Preethy · 2012
Group communications are important in mobile Ad hoc networks. Multicast is an efficient method for implementing group communications. However, it is challenging to implement efficient and scalable multicasting in MANET due to the difficulty in group membership management, multicast packet forwarding and the maintenance of multicast structure over the dynamic network topology for large group size or network size. The existing EGMP (Efficient Geographic Multicast Protocol) protocol uses virtual-zone-based structure to implement scalable and efficient group membership management. It makes the position information to guide multicast routing. The existing protocol is designed to be comprehensive and self-contained, simple and efficient for reliable operation. The proposed method use Stateless based EGMP Routing Protocol. The stateless routing used in two nodes has the same residual energy level. An active node that is used in many data-forwarding paths consumes energy more quickly and it has a shorter lifetime than the remaining inactive node. The geographic locations of the nodes remove the need for costly state maintenance making it ideally suited for multicasting in dynamic networks. It reduces the time complexity of routing packets. The simulation results demonstrate that stateless based EGMP has higher delivery ratio under all circumstances with different moving speeds and node densities. The proposed Stateless EGMP protocol is compared with Ad-hoc On-demand Distance Vector (AODV) and EGMP. It has significantly reduced the link failure, low control overhead and multicast group joining delay. The proposed work shows more efficiency than the existing work.
