Abstract:
Recently, the necessity of applications where many
users have to interact in a close manner over mobile Ad-Hoc
networks gains high popularity. Multicast communication is
essential in this type of applications to reduce the overhead of
group communication. For group-oriented multimedia
applications Quality of Service (QoS) provision is a basic
requirement, which makes an efficient QoS multicast routing
protocol a very important issue. This paper proposes a locationbased QoS multicast routing protocol via cooperation between
Network and MAC layers. Along with this protocol, a location
and group membership management scheme has been proposed.
Unlike some of multicast routing protocols, the proposed
approach limits maintaining the network topology to certain
nodes to reduce control overhead and reduce bandwidth
consumption. Our proposed protocol is scalable for large area
networks with large multicast members regardless of the network
density. Also, it achieves a significant reduction in processing
overhead compared to flat QoS algorithms.
