    Abstract:

    The precision of DV-Hop localization algorithm is not good enough when it is used to compute the distance value between unknown nodes and beacon nodes. To overcome its disadvantage, a precision improved algorithm based on DV-Hop is proposed. The three neighboring nodes in the route of the unknown node to the beacon node are analyzed, and an improced DV-Hop Location Algorithm based on the Ordered Neighboring Nodes in Space is proposed. Simulation proves that the improved algorithm is effective and feasible.
