Summary: Abstract
In today's wireless networks, different users with different
bandwidth (B.W.) requirements, and different quality of service
requirements (QoS) are competing for the network bandwidth.
The decision to admit or reject a call is made by the call admis-
sion protocol. That decision is based on the requested band-
width, the network utilization, and the priority of the incoming
call. In this paper, we assume a cellular system where different
users with different B.W. requirements, different QoS require-
ments and different priorities are competing for admission. We
present a new call admission protocol. Our proposed protocol
makes the admission decision based on the network utilization,
the incoming call priority, and the incoming call's BW require-
ments. We present simulation results for our protocol and com-
pare it with existing protocols. Our simulation results show that
our protocol can better control the different rejection ratio ac-
cording to priority without sacrificing the network utilization.
