Channel Allocation and Power Control Based on Differential Evolution Algorithm in Cognitive Radio Mesh Network
摘要
Abstract
Channel allocation plays an important role in improving the performance of cognitive radio mesh network.Considering the influnce of the node power on network interference, the network interference edge and potential interference edge are defined.By quantizing the level for communication power, a network model of joint power control and channel assignment is presented.Futher,the channel allocation algrithm with power control on the basis of differential evolution algorithm is proposed.The real-number encoding rules and relevant constraints control mechanisms are designed to ensure the effectiveness of the individuals, thus to converge faster to optimal solution.Extensive simulations have been performed to validate the effectiveness of the proposed algorithm.关键词
