Therefore, effectively utilizing the limitedresources of ic spectrumand thoroughly maintaining munication qualities e one of the mostimportant issues in the management system of a work. To address this issue, channel assignment objective of channel assignmentis to assignchannels to mobile terminals and base stations such that work?s capacity, in terms of numbersof mobile usersand no interferenceconflicts, is capacity is maximal when the call-blocking and hand-over failure probabilities are previous works have been done in reducing plexity of solving theseproblems, but for real time traffic, their designs are suffer from a few challengessuch as:?Practicaldeployment of channel assignmentin large worksSince channel assignment problem (CAP)is plete, putational intelligenceapproachesproposed in order to find a channel assignment that satisfies the hard constrains: co-channel constraint, adjac
