| 摘 要： | 定位技术是传感器网络中的关键技术之一。重点介绍DV-Hop，ROCRSSI两种分布式非测距定位算法及具体实现过程，DV-Hop算法以增加网络通信开销为代价获得了较高的容错性和覆盖率；ROCRSSI算法简单、部署成本低，但对周围环境和锚节点密度依赖性较大。从开销、容错性、定位精度、覆盖率等方面对两种算法的具体性能做了评价比较。

| Abstract: | Node localization is one of the most critical technologies in wireless sensor networks.Mainly introduced the concrete processes of DV-Hop and ROCRSSI localization algorithms.DV-Hop algorithm had higher coverage and fault-tolerant,while increased the communication overhead;ROCRSSI algorithm was simple and had lower cost,but relied on environment and the density of the anchor nodes.Finally evaluated the performances of the two algorithms from overhead,accuracy,coverage,fault-tolerant and so on. |
