Description: 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.
