蚁群聚类能量分簇在802．11无线网络定位中的应用

摘要

IEEE 802．11无线网络以快速灵活的组网方式得到广泛部署和应用，其定位方法也成为近年研究热点。论文提出了一种基于蚁群聚类能量分簇RSSI指纹定位算法，利用蚁群信息素反馈机制优化能量聚类分簇和收敛速度，再根据能量指纹匹配定位节点位置。仿真实验表明，该算法定位精确，能很好地减小由信号波动引起的定位误差。%IEEE 802 .11 wireless network is widely deployed and adopted because of its high‐speed and flexible networ‐king .The locating methods have become hot topic in this years .This paper first describes the questions based on current Lo‐cating methods in wireless network ,and propose a fingerprint‐based ant clustering RSSI location algorithm using feedback mechanism and clustering .Simulation results show that new algorithm has high locating accuracy ,can reduce positioning er‐rors caused by the signal fluctuations .
