【Abstract】 Based on the traditional positioning technology of DV-Hop algorithm,through analysis of the main reason for the error occurring in the algorithm,this paper proposes the correction method of Hop count between nodes. Double frequency is used in radio communication. The hop count between nodes can be reduced to 0. 5R,which can reduce the average jump distance error. Through matlab software experimental verification,this algorithm can improve the node location accuracy.The higher frequency of network communication can further make the positioning accuracy lower. Positioning results reached the expected purpose.更多还原
