Abstract:
Abstract—Multicasting communication serves as one critical
operation to support many applications of Mobile Ad hoc
networks (MANETs) that achieve group communication rather
than pairs of individuals. Multicast routing protocols becomes
increasingly important in MANETs because they effectively
coordinate a set of nodes. Also, it provides efficient routing for
multimedia applications such as video conferences, military
and rescue operations. Such applications are highly demand
for Quality of Service (QoS), which makes an efficient QoS
multicast routing protocols is very important. In this paper, we
propose a model that searches for QoS paths from a single
source to a set of destinations. The physical area is partitioned
into equal size hexagonal cells and a leader and backup leader
nodes is elected to maintain up-to-date information about the
network topology. Efficient routing is performed based on
nodes positions to deliver data packets to all the receivers. The
simulation results show that, comparing with the well-known
multicast protocol ODMRP (Demand Multicast Routing
Protocol), PBQMRP achieves less packet drop ratio with
significant reduction in control overhead.
