Abstract :
In this paper, we propose a new efficient borrowing channel assignment (BCA) scheme, which consists of two phases. The first ordinary channel allocation phase borrows a channel from neighboring cells by an impact-based borrowing strategy. The second channel reallocation phase has a reallocation procedure for locked-channel utilization and a reallocation procedure for efficient channel reuse. Simulation results show that in both uniform and nonuniform traffic cases, our schemes significantly reduce the system blocking probability over the other existing schemes. Furthermore, one of our schemes has a much smaller number of reallocations than other compared schemes
