Dynamic channel allocation based on compact pattern concept with pattern restoration: performance analysis of a modified approach

With limited frequency spectrum and a tremendous growth in the demand for mobile communication services, the problem of channel assignment becomes increasingly important. A modified extension to the traffic-adaptive non-uniform compact pattern assignment algorithm is presented, which can be exploited in a PCS cellular environment with highly mobile users. The proposed dynamic channel assignment scheme copes with the handoff originated call demands problem as well as focusing on reduction of the blocking probability of the new calls. Computer simulation results on a 49-cell network conducted in a different manner and environment comparing to previous studies indicate superior teletraffic performance of the proposed strategy over its predecessors. By using a discrete time step model traffic simulator, the effect of users mobility on the grade of service has also come under study in this research.
