Abstract

Now a day’s Mobile ad-hoc networks became a popular subject for research due to its wide utilization in different areas, and various studies have been made to increase the performance of ad hoc networks and support more advanced mobile computing and applications. Multicasting is a useful operation that facilitates group communications in MANETs. There are some problems of the existed mobile computing applications are multicast group membership management, zone construction and efficient forwarding of packets to all the group members over the dynamic network topology for a large group size or network size. This paper concentrated specifically, on efficient packet forwarding through a virtual-zone-based structure, and the location service for group members is integrated with the membership management. Both the control messages and data packets are forwarded along efficient tree-like paths, but there is no need to explicitly create and actively maintain a tree structure. The stateless virtual-tree-based structures significantly reduce the tree management overhead, support more efficient transmissions, and make the transmissions much more robust to dynamics. By upgrading the USVGM protocol with virtual-zone-based structure and tree-like paths we achieved higher performance and reliable and scalable data packet forwarding. Our simulation results demonstrate that Upgraded SVGM (USVGM) has high packet delivery ratio, low control overhead and multicast group joining delay under all test scenarios, and is scalable to both group size and network size.
