A Channel Borrowing Assignment Strategy with Directional Locking in Mobile Communication Systems

The authors propose an optimized compact pattern based channel borrowing assignment (CPCB) strategy, that is, the compact pattern based channel borrowing assignment strategy with directional locking (CPCBDL). This strategy notonly introduces the advantage of directional channel locking concept, but also optimizes the mechanism of channel management. Simulation is done in a universally used network. The system performances under a kind of uniform and two kinds of non-uniform traffic distributions. The simulation results show that the CPCBDL performances are superior to those of FCA, BDCL and CP based DCA, etc., and even outperform those of CPCB. This improvement is very important to improving the spectrum efficiency and throughput in cellular communication systems.
