Performance analysis of cellular systems with dynamic channel assignment

摘要

We present a quasi-analytical method to compute the call blocking probabilities at a particular traffic density in a cellular system that employs dynamic channel assignment. The method is based on enumerating all the states in the entire state-space, a task that is beyond the capabilities of even the fastest computers when the cellular system has many cells and channels. We show how this task can be done by only focusing on the same system having just one channel. The results demonstrate that our combinatorial approach is very accurate.
