摘要

Wireless Sensor Network (WSN) which is composed of lots of self-organizational intelligence nodes has become new technology of information acquisition and processing. Location technology is one of the key technologies in WSN. There are many kinds of location algorithms currently and the research to performance evaluation and applicability analysis of algorithms has fundamental significance. For this reason, the paper firstly elaborated the performance evaluation indexes of location algorithms, and analyzed the location prin-ciples, characteristics and current fundamental problems to typical and some new location algorithms, and then analyzed and compared some typical location algorithms according to the location accuracy, node den-sity and hardware requirement, obtaining the sphere of application of these algorithms and pointing out the problems which need to be solved in WSN currently.
