Improved frequency channel borrowing and locking algorithm in cellular mobile systems

In this paper, an new algorithm for frequency channel allocation in cellular mobile systems is proposed and examined in comparison with a dynamic load balancing strategy for channel assignment using selective borrowing in cellular mobile environment and a new adaptive channel assignment algorithm in cellular mobile system. When making a borrowing decision, the states of the co-channel cells of a potential lender cell are also taken into account to prevent potential channel borrowing loop. The proposed algorithm provides a co-channel locking scheme that efficient to avoid the co-channel interference and reduce the number of locking co-channel cells. A simulation model was designed by C-Free languages to measure the performance of our algorithm. Results show that new algorithm provides the number of channel borrowing is highest and number of locking co-channel cell is lowest.
