An Improved Algorithm of the Node Localization in Ad Hoc Network

Abstract—If the destination node is far from the source node, the transmission of the routing control information for the destination node has some delay and will then affect the accuracy of the node localization. An algorithm is proposed to predict the actual location of the destination node based on its current position information in routing table. The original algorithm is analyzed, and the primary reason that the node localization has some deficiency is pointed out. The node localization forecast algorithm is designed and realized, and the forecast algorithm is used to improve the accuracy of the node localization as far as possible. The algorithm is simulated and analyzed, and it proved that the proposed algorithm can effectively reduce the impact of positioning accuracy caused by the node transmission delay and other factors
