Prioritized channel borrowing without locking: a channel sharing strategy for cellular communications

We previously suggested a new channel sharing method for cellular communications. The method, called channel borrowing without locking (CBWL), allows real-time borrowing of channels from adjacent cells without the need for channel locking in co-channel cells. CBWL with cut-off priority for calls that arise in the cell is presented. This scheme discourages excessive channel lending and borrowing at high traffic load and promotes a more uniform grade of service throughout the service area. An analysis using macro-states and decomposition is devised to evaluate the performance of the scheme. The results are validated by simulation
