摘　　要：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.It is a challenge for source location privacy research. Although there are so much research have been done on source location privacy,it is still have much work to do. A novel multi-redundant branch combined with spiral routing policies is proposed to protect the source location privacy effectively. The main core of the strategy is ： First, spiral backbone route is established; Then, redundant false branch route is created in the area where the energy is abundant. The false branch branches with the real source routes are brought together to spiral backbone route. Thus the true source routing is mixed with the many false routing, thus the source location privacy is enhanced. On the other hand, although this strategy increase a large number of branch routes. However, due to redundant false branch route is built in the area where the energy is abundant,and thus does not affect the network lifetime. Both theoretical and simulation re- sults show that the proposed scheme significantly improves privacy strength about 2-4 times, while the network lifetime equal with re- lated studies.
