Abstract :
RSSI localization algorithm and DV-Hop localization algorithm are the typical representatives of the range-based and free-range localization algorithm of wireless sensor networks respectively. In this paper, the reasons for localization error caused by the RSSI localization algorithm and DV-Hop localization algorithm are analyzed, on this basis, a union node localization algorithms based on RSSI and DV-Hop is put forward, in order to decrease the ranging error, the method of measure distance is chosen based on hop count. The implementation process of the union localization algorithm is supplied, and the performance of the algorithm is simulated. The simulation results show that the positioning accuracy of the union localization algorithm has significantly improved.
