Summary: Abstract
Call admission protocols play a central role in determining both the
performance of any network, and the revenue of the network. The call
admission protocol must decide either to accept the call or reject it,
Thus having an impact on both the quality of calls and the network rev-
enues. The call admission protocol must deal with multiple classes of
calls having different requirements, requesting different quality of ser-
vice and with different priorities. In this paper, we propose a protocol
for call admission control in cellular networks. Our protocol can effec-
tively deal with multiple traffic classes each with different bandwidth
requirements and different priorities. We also present simulation re-
sults for our protocol and compare it with existing protocols. Simula-
tion results show that our protocol can give preferential treatment for
high priority traffic without affecting the network utilization.
Key words: call admission protocols, bandwidth allocation,
fairness, cellular networks
1. Introduction
When a call requests admission in a specific cells, the call ad-
mission control protocol must decide either to accept or reject
this call. In making he decision to accept or reject the call many
