Abstract

The localization technology based on beacon-free node can significantly reduce the network cost when it takes into account the configuration constraints and cost factors of wireless sensor network as well as satisfies the lower hardware requirements. This inspires the wireless sensor network node localization studies. With an analysis of the beacon nodes and beacon-free node localization algorithm, this paper puts forward the localization algorithm of wireless sensor network beacon-free node probability-based. Simulation results show that the algorithm, at no additional hardware, will reduce the computation overhead and improve the localization accuracy and that has good adaptability.
