A Localization Algorithm Based On The Irregular Topology For Wireless Sensor Network

摘要

Through analysis of the theoretical of the localization algorithm, we conclude that DV-HOP algorithm in irregular network topology(existence of empty positions, and the isolated sensor nodes), the algorithm performance is not satisfactory. We propose a DV-HOP algorithm used in the irregular network topology: Irregular Topology DV-HOP (ITDV-HOP) algorithm, the main aim of the algorithm is to improve the nodes positioning accuracy in the irregular network topology. Through our simulation study, comparing the DV-HOP algorithm in irregular topology of the network effect, the ITDV-HOP algorithm in irregular network topology, the positioning accuracy improvement effect is remarkable.
