QOS Multicast Routing Based on Bandwidth and Resource Availability in Mobile Adhoc Networks

The need for supporting real time and multimedia applications for users of Mobile Ad hoc Network (MANET) is becoming essential. Mobile ad hoc networks can provide multimedia users with mobility they demand, if efficient QoS multicast strategies were developed. The aim of this paper is to define the building blocks of such an Ad hoc QoS Multicasting (AQM) protocol and propose a cross layer framework to support QoS multicasting. AQM achieves multicasting efficiency by tracking the availability of resources for each node within its neighbourhood. Computation of free bandwidth is based on reservations made for ongoing sessions and similar information reported by neighbours.
