Improved Random Incomplete Coloring for Interference Mitigation in Wireless Body Area Networks

摘要

摘要: 该文在基于随机不完全着色干扰避免资源调度算法基础上，提出一种改进式随机不完全着色算法以优化无线体域网间干扰协调，通过控制已着色节点继续参与下一轮的着色算法实现网络更高的资源空间复用，通过限制相邻节点分配颜色数量差距保证节点间资源分配的公平性。仿真结果表明该文所提改进式随机不完全着色算法可在避免无线体域网用户间干扰的同时，进一步提高网络吞吐量和频谱空间复用率。

Abstract: An Improved Random Incomplete Coloring (IRIC) algorithm is proposed based on Random Incomplete Coloring (RIC) to mitigate inter-Wireless Body Area Network (WBAN) interference. The proposed IRIC algorithm can realize high resource spatial reuse by controlling colored nodes to participate in next round of coloring, and the fairness is also guaranteed by restricting the gap of assigned color amounts between adjacent nodes. Simulation results show that the proposed IRIC algorithm can further improve the system throughput and resource spatial reuse.
