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

摘要

摘要: 該文在基于隨機(jī)不完全著色干擾避免資源調(diào)度算法基礎(chǔ)上，提出一種改進(jìn)式隨機(jī)不完全著色算法以優(yōu)化無線體域網(wǎng)間干擾協(xié)調(diào)，通過控制已著色節(jié)點繼續(xù)參與下一輪的著色算法實現(xiàn)網(wǎng)絡(luò)更高的資源空間復(fù)用，通過限制相鄰節(jié)點分配顏色數(shù)量差距保證節(jié)點間資源分配的公平性。仿真結(jié)果表明該文所提改進(jìn)式隨機(jī)不完全著色算法可在避免無線體域網(wǎng)用戶間干擾的同時，進(jìn)一步提高網(wǎng)絡(luò)吞吐量和頻譜空間復(fù)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.
