Abstract:

This paper studies the localization algorithms of wireless sensor networks, introduces the current research status of localization and a localization  algorithm using the concept of ring-overlapping. The disadvantage of this algorithm is also pointed out; two possible improvements are given and compared with each other. Through a theoretical analysis and emulation, two proposed algorithms are proved to have higher performance.

Key words: wireless sensor network, localization algorithm, ring-overlapping, anisotropy
