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

Publiceringsår: 2004
Språk: Engelska
Dokumenttyp: Konferensbidrag


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.
