Abstract

Aiming at characteristics of limited energy of networks

concentrated nodes and is adapted to dynamic change of the wireless sensor networks（ WSNs）

a localization algorithm of two-wheeled cooperative based on nodes selection received signal strength difference（ RSSD） is proposed to solve the problem of uncooperative passive localization. On the basis of the first round result

regular polygon matching factor is proposed to select the optimal nodes in the space domain to get the final localization result and improve the localization precision.Simulation results show that the proposed method combines the characteristics of WSNs and make full use of influence of space position. By comparing the simulation

the effectiveness of this method is proved.
