ABSTRACT
Wireless networks become more widely used to support advanced services. Traditional
approaches to guarantee quality of service (QoS) work well only with predictable channel and
network access. The Multicast transmission is a more efficient mechanism when compared to
uni-casting in supporting group communication applications and hence is an important aspect
of future network developments. To enable high QoS for all admitted traffic, the Admission
Control monitors the wireless channel and dynamically adapts admission control decisions to
enable high network utilization while preventing congestion. Mobile Adhoc networks can
provide multimedia users with mobility, if efficient QoS multicast strategies were developed. In
load balancing QoS Multicast Routing QMR, constant available bandwidth for the link is
assumed. A cross-layer framework to support QoS multicasting is extended for more effective
than QMR. The extension reflects good packet delivery ratios associated with lower control
overhead and lower packet delivery delay. If minimum real-time requirements are not met,
these unusable packets waste scarce bandwidth and hinder other traffic, compounding the
problem. Whereas the dynamically adapted mobility with control overhead monitors the high
QoS for all admitted traffic, and the bandwidth for each node is enhanced to reflect the good
packet delivery ratio associated with lower control overhead and lower packet delivery delay.
