Abstract :
Channel Borrowing Without Locking allows real-time borrowing of channels from adjacent cells without the need for channel locking in co-channel cells. CBWL provides enhanced traffic performance in homogeneous environments and also can be used to relieve spatially localized traffic overloads. It can be applied in the cellular systems without additional costly infrastructure. CBWL permits simple channel control management and easy implementation. This paper describes "fast channel returning", an enhancement of the CBWL scheme. With fast channel returning, a borrowed channel is returned as soon as a regular channel becomes available. CBWL with fast returning reduces unnecessary channel borrowing and improves the performance of CBWL. Systems are modeled by multi-dimensional birth-death processes. An efficient method that uses macro-states, decomposition, combinatorial analysis and convolution algorithm is devised to find blocking probabilities. The results, which are also validated by simulation, indicate that channel fast returning can enhance system performance of CBWL scheme
