摘要
Abstract
Aiming at the DV-Hop algorithm vulnerable to the effect of wormhole attack,three aspects of improvement are presented: (1) a new hop set method is put forward which is used when wormhole attacks is discovered between nodes. If discovering wormhole attack, the hop between anchor nodes will be replaced with the reasonable hop calculated by the designed nonlinear formula. (2) a method of affirming the position of wormhole link is presented. Through this method, it can not only confirm the position of the wormhole link, but can obtain get the node number directly affected by wormhole attack. (3 ) it can determine whether to reposition according to the statistical node number. If necessary,those data got during the first positioning is used to bypass wormhole links. Theoretical analysis and simulation results show that the proposed algorithm does not need auxiliary and expensive hardware,only through a simple calculation lo resist the wormhole attacks effectively, so the algorithm is not only easy to implement, but also has low traffic and relatively small positioning error,therefore suitable for the large-scale network applications.关键词
