针对以往源节点位置隐私保护研究中存在的不足.提出一种基于多冗余分支汇集螺线的路由策略来有效保护源节点位置.策略的主要核心是:首先通过建立螺旋状主干路由;然后,在节点能量较为充裕的区域产生多个虚假的分支路由,这些虚假的分支路由与真实源节点的分支路由都汇集到螺线状主干路由上.从而将真实的源节点产生的路由分支隐蔽在众多的虚假分支路由中,因而起到了增强源节点隐私保护的目的.从另一方面,本文的策略虽然增加了众多的干扰分支,但是,由于干扰分支的产生都是在能量充裕的区域产生的,因而并不影响网络寿命.经过本文的理论与实验分析结果表明,本文的策略在隐私保护强度上面提高了数倍,而网络寿命与相关研究相等.
Aiming at the shortcomings of previous research on privacy protection of source node location, a routing strategy based on multi-redundancy branch spirals is proposed to effectively protect the location of source node.The main core of this strategy is: firstly, the spiral backbone route is established; A plurality of fake branch routes are generated in a region where the node energy is abundant, and these fake branch routes and branch routes of the true source nodes all converge on the spiral backbone route, so as to hide the routing branch generated by the real source node in numerous Of the false branch routing, and thus has the purpose of enhancing the privacy protection of the source node.On the other hand, although the strategy of this article adds a large number of interference branches, the generation of interfering branches is generated in an energy-abundant region, Thus does not affect the network life.According to the theoretical and experimental analysis results show that the strategy in this paper increased several times in the privacy protection, and the network life is equal to the related research.
