AN EFFICIENT BORROWING CHANNEL ASSIGNMENT SCHEME FOR CELLULAR MOBILE SYSTEMS

In this paper, we propose a new efficient borrowing channel assignment (BCA) scheme, which consists of two phases. The first ordinary channe l allocation phase borrows a channel from neighboring cells by an impa ct-based borrowing strategy, The second channel reallocation phase has a reallocation procedure for locked-channel utilization and a realloc ation procedure for efficient channel reuse. Simulation results show t hat in both uniform and nonuniform traffic cases, our schemes signific antly reduce the system blocking probability over the other existing s chemes. Furthermore, one of our schemes has a much smaller number of r eallocations than other compared schemes.
