摘要针对传统非基于测距的定位算法仅用二进制数评估连接与否而没有基于单纯的连通性导致定位误差增加的问题,基于1跳内相邻节点间距离的远近关系,提出了一种调整特征距离(CSD)算法。作为一个透明的支撑层,只需较少额外成本。仿真实验表明:嵌入CSD后的定位算法可以有效提高定位精度。 Aiming at the problem that the traditional positioning method uses binary number to evaluate connectivity instead of pure connectivity, which results in increasing of positioning error. A range-free localization algorithm named correction signature distance（CSD） algorithm based on distance between adjacent nodes within 1 hop is proposed. As a transparent support layer, it only needs less extra cost. Simulation results show that the localization algorithms embedded by CSD can effectively improve positioning precision.
