SRMAODV: A scalable reliable MAODV for MANET

Abstract

Many networking applications such as video-on-demand services, video conferencing, and distributed database replications require multicast communications. Providing scalable and reliable multicast are basic requirements to develop a better routing protocols which is used for disaster management, emergency relief, mobile conferencing among many other applications. As mobile host changes its access point over a time interval, multicast routes have to be updated frequently. This poses several challenges to provide an efficient multicast routing. In this paper, we propose a Scalable Reliable Multicast Ad hoc On Demand Distance Vector (SRMAODV) protocol based on Ad hoc On Demand Distance Vector (AODV) and Multicast AODV (MAODV) protocol to support scalability and reliability for online routing of delivery-guaranteed multicasts. Exhaustive simulation experiments reveal that Packet Delivery Ratio (PDR) which is an important measure of reliability for SRMAODV is much better together with improved end-to-end delay.
