Uplink Status Based Dynamically Optimized Channel Assignment

In this paper,a new model of channel assignment based on the carrier to interference ratio (CIR) of the uplinks in cellular mobile networks is presented.Compared with the classical compatibility matrix model,the new model is more accurate and is adequate for analyzing the interference adaptive channel assignment scheme.For comparison purpose,an improved genetic algorithm developed from the genetic algorithm and Tabu search for solving the channel assignment problem (CAP) is also proposed.Both analysis and simulation show that the new model can describe practical systems more precisely,and can lead to more efficient resource utilization when employed to solve CAP.
