摘　　要：分析了HCRL定位算法的原理和过程,在继承了HCRL低系统通信开销优点的基础上,针对其在计算复杂度和定位精度方面的不足,应用了3种改进策略———基于节点无线射程的改进策略、基于等比点的改进策略和基于等力点的改进策略,提出了改进的IMP-HCRL算法。仿真实验表明:IMP-HCRL定位算法不仅保持了HCRL在节省系统通信量上的优势,同时提高了定位精度,降低了系统的计算复杂度。The principle and process of HCRL algorithm are analyzed.A novel node positioning algorithm,called IMP-HCRL,is proposed,which adopts three improvements,including the strategy based on wireless transmission range,the strategy based on bisector point and the strategy based on isodynamic point,to overcome the drawbacks at computational complexity and localization accuracy of HCRL with low communication overhead simultaneously.The simulation shows that the IMP-HCRL is better than the HCRL in both aspects mentio...
