摘要：
To deal with the inaccuracy and the uniform distribution of the DV-Hop algorithm, it is necessary to put forward a new optimization algorithm based on DV-Hop and RSSI for the two-dimensional planar node location called RSDV-Hop. The algorithm is based on the shortest hop distance with RSSI algorithm and gets the position between the nodes and the anchors according to the difference of signal strength. Moreover, it estimate the distance between the nodes and the anchors on the basis of the difference of signal strength. Therefore it can reduce the influence of the error of signal strength and the distance as far as possible by choosing different localization algorithm based on the different relationship of the nodes and the anchors. Experimental results show that the proposed algorithm performance well on the positioning accuracy and have better success rate than the DV-Hop and WPDV-Hop.
