Due to the fact that the DV-Hop algorithm has low positioning accuracy while the RSSI algorithm is greatly affected by environmental factors, this paper presents a BRDV-Hop algorithm by combinning the character of RSSI and DV-HOP. To improve computational efficiency, the RSSI distance measuring technique is intergrated into the presented algorithm. By utilizing the distance measuring technique, the average hop distance difference of beacon node is firstly defined, and then the distances of unknown nodes and the beacon nodes are adjusted by using the average hop distance difference of the beacon nodes, such that the location difference is significantly decreased. Simulation results show that, without increasing the sensor nodes, improved algorithm performs much better than the standard DV-Hop algorithm.
