基于用户需求的改进型频谱资源分配算法
Advanced Spectrum Resource Allocation Algorithm Based on User Requirement
摘要
Abstract
In the wireless communication,reasonable effective allocation in the limited frequency is the key to realize cognitive radio net-work. According to the difference of the cognitive user’s requirement and the dissatisfied user’s demand,put forward an improved spec-trum resource allocation algorithm by the research of the preceding spectrum allocation algorithms which were built on the graph coloring theory. Analyzing the user’s demand,comparing the requirement with the utility,it seeks the user who has the most demand and maxi-mum utility and allocates it homologous spectrum. During the process of distribution,it updates the user’s needs to improve user’s satis-faction. Simulation results indicate that this algorithm can make the allocated frequency meeting the user’s requirement as soon as possi-ble,minimize the user’s unsatisfactory bandwidth demand and further raise the utilization rate of spectrum. So the advanced algorithm has superior in the performance.关键词
