Abstract:

This paper proposes a collaboration ripple algorithm for high accuracy, large range and low cost localization of large scale nodes in a wireless sensor network (WSN). A splicing network topology is designed based on a rational network topology research. Location error is reduced with collaboration among the nodes. The ripple algorithm is applied to locate unknown nodes in a unit cell to realize accurate localization of
neighboring notes. Verification of the algorithm shows that the collaboration ripple location algorithm can reduce anchor nodes by 3.20%, and improve precision by 20.00%, indicating effectiveness of the proposed algorithm.

Key words: wireless sensor network (WSN), localization, high accuracy, network topology divide, collaboration ripple localization algorithm
