摘要
针对无线传感器网络中节点定位精度不准的问题,提出改进布谷鸟搜索算法的无线传感器节点定位方法。将布谷鸟搜索算法应用于节点位置寻优问题中,同时对布谷鸟搜索算法的补偿以及发现概率进行优化,以保证测距误差对实际定位误差的影响,提高节点定位的精确度。经过对比实验验证:基于改进布谷鸟搜索算法的无线传感器节点定位方式相比其他方式效率更高,定位精度更高,具有更好的实时性和稳定性。
In order to solve the problem of inaccurate node positioning accuracy in wireless sensor network,a wireless sensor node positioning method with improved cuckoo search algorithm is proposed.The cuckoo search algorithm is applied to the node position optimization problem,and the compensation and discovery probability of the cuckoo search algorithm are optimized to ensure the influence of the ran-ging error on the actual positioning error and improve the accuracy of node positioning.Comparative ex-periments show that the wireless sensor node positioning method based on the improved cuckoo search algorithm is more efficient,has higher positioning accuracy,and has better real-time and stability than other methods.
