Distributed Channel Allocation Algorithm with Power Control

In this paper, we integrate the channel assignment and power assignment into a distributed channel access algorithm. A cost-function is introduced to provide some optional channels according to their cost for transmitted power level searching. The simulation results show that this algorithm largely increases capacity compared with the fixed channel allocation (FCA). The proposed algorithm can adapt to the call saturated state of network and does not cause high intracell handover access. It has a short average call setup time even at high traffic loads. We suggest that the intracell handover rate should be a factor in evaluation of an algorithm’s performance, because high handover access will intensively increase the load of switch and cause much higher call dropping and blocking probabilities than those we expect.
