Abstract:
Recently, the necessity of applications where
many users have to interact in a close manner over mobile AdHoc 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
location-based 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. To further reduce the control overhead and
bandwidth consumption, we apply clustering strategy by
partitioning the network topology into hexagon cells. Thus,
maintaining the network topology is limited to certain nodes.
The performance of the proposed protocol is evaluated using
GloMoSim simulation environment. Simulation results show
that our approach provides high packet delivery ratio
associated with low control overhead.
