This paper proposed a novel tracing time-constrained routing algorithm to achieve privacy protection.The core idea is that the routing path from the source node to the sink is generated and distributed dynamically and randomly,and its lasting time is shorter than the time for adversary to trace to the phantom node,then it is more difficult for the adversary to trace to the source,and thus increase the protection strength.The difficulty of this algorithm is that under the multi-to-one data collection mode and with limited energy,how to generate dynamic and long enough path in the region of abundant energy and generate only necessary path in the region of tension energy,and thus achieve privacy protection as well as network lifetime maximization.We transferred this problem into lifetime maximization with limited energy and then gave the solution.Through theoretical analysis and large number of experiments,results show that the algorithm in this paper can greatly improve the source location privacy with lifetime no less than lifetime in previous research.
