Compact pattern based channel borrowing assignment strategy in cellular mobile systems

This paper proposes a new dynamic channel assignment strategy called compact pattern based channel borrowing assignment strategy (CPCB). The new strategy combines the advantages of compact pattern dynamic channel assignment with fixed channel assignment with channel borrowing. Compared with the average blocking probabilities of fixed channel assignment (FCA), borrowing with directional channel locking (BDCL), compact pattern based dynamic channel assignment (CPDCA) and compact pattern with maximized channel borrowing (CPMCB) in various uniform and nonuniform traffic load distribution, it is shown that, with the increase of traffic load, the system average blocking probability of CPCB is lower than that of above strategies. Besides, the growth rate of the probability is also lower than that of the above strategies significantly.
