Abstract: Compared to wired networks, the communication bandwidth in the wireless networks
is limited. In trying to achieve QoS guaranteed wireless services, efficient utilisation of
bandwidth resources becomes a fundamental issue. A number of channel allocation schemes
have been proposed to fully utilise the wireless bandwidth, but many of them just proposed the
channel allocation scheme without presenting a specific channel allocation model. In this
paper, we propose and analyse three different channel allocation schemes for wireless networks.
We build three system models based on a two-dimensional Markov chain to compute the
performance of base station in terms of the new call blocking probability, the handover dropping
probability, and the channel utilisation.
Keywords: channel allocation; handover; performance evaluation; wireless networks.
