Multicast routing for ad hoc networks with overload prevention for group members

Mobility, quality of service (QoS) support, and multicast
routing capability are important requirements for today’s
networks. This is a result of the changes in wireless users’
expectations, which favour group-oriented, high-quality,
multimedia communication. Ad hoc networks enhanced
with QoS multicasting strategies can provide users with
these features. This paper defines the building blocks of an
ad hoc QoS multicasting (AQM) protocol, which tracks the
availability of resources within a node’s neighbourhood
based on reservations made previously, and announces it at
session initiation. When nodes join a session with certain
QoS requirements, this information is updated and used to
select the most appropriate ro
utes. AQM is compared to a
non-QoS scheme with particular emphasis on preventing
overload on multicast group members. It achieves better
results through the use of its QoS-related routing decisions,
which suggests that QoS is both essential for and
applicable to multicast applications in ad hoc networks.
