Several DCA schemes have been proposed to improve the quality and carried traffic in mobile cellular radio system. Most of these schemes assign channels to calls based on the constraint imposed by cochannel interference, and ignore the ACI (adjacent channel interference) constraint. Incorporating the ACI constraint results in increasing the blocking probability. In order to overcome this problem we propose a new channel allocation scheme based on the minimum cost function and “channel swapping idea. The scheme involves, swapping the assigned channels from the interfering cells to assign a channel for a call request which is about to fail. Performance evaluation of the proposed scheme is carried out by computer simulation in terms of carried traffic and call blocking, and compared with other DCA schemes of [1], [2], and [3].
