Abstract

This paper proposes a new distributed dynamic channel assignment scheme, called channel borrowing with interference information (CBWI). Each cell selects a channel based on the information provided by its interference information table (IIT). CBWI does not require system-wide information. The IIT contains information about the local cell and its interfering cells. The channel assignment strategy attempts to minimize the effect on the availability of channels in interfering cells. Intra-cell channel reassignment and inter-cell single channel reassignment are used to further reduce the call blocking probability. Simulation results show that CBWI provides the lowest call blocking probability compared to other existing schemes in both uniform and nonuniform traffic distributions. It was found that inter-cell double channel reassignment does not reduce the call blocking probability by much
