Route construction method with strong source position privacy protection capacity

Abstract

The invention discloses a route construction method with a strong source position privacy protection capacity. The route construction method comprises the following steps: firstly, creating a phantom node P according to the existing phantom routing policy; secondly, creating a first branch route formed by PA and PT by the phantom node P according to set hop count fai; thirdly, creating a main trunk routing path by a middle node A; finally, creating interference branch routes by nodes on the main trunk routing path. According to the method, only the main trunk routing path is created in an area with high network energy consumption, and the energy consumption of an energy cavity area is not increased, thus the life of a network is not reduced, the excess energy away from Sink area nodes is adequately utilized, and the interference branch routes are created as much as possible in an area with adequate energy; a very strong source position privacy protection capacity can be achieved on the basis of the novel tree routing policy of redundancy interference routing paths, meanwhile, the network achieves energy balance, and the life of the network is maximized.

Description

technical field [0001] The invention relates to a routing construction method with strong source location privacy protection capability. Background technique [0002] Wireless Sensor Network (WSN) is a wireless network composed of a large number of stationary or moving sensors in a self-organizing and multi-hop manner, with the purpose of cooperatively sensing, collecting, processing and transmitting the information of sensing objects in the geographical area covered by the network. Monitor information and report to users. When any sensor node N detects information, it will send monitoring information to the neighbor node A closest to the base station (Sink), and A repeats the actions of node N until the signal is finally received by the base station. The wireless sensor network based on this process will have security and energy holes and the effectiveness of routing mechanisms and protocols. [0003] First, in terms of security. In the research based on phantom routing,...

Problems solved by technology

Therefore, how to make the real source node notify the fake source node to send fake data synchronously when there is data is currently a very difficult thing, and the fake source that is not synchronized is often more likely to expose the real source node

In addition, the problem of high energy consumption of false sources has always been another biggest problem that makes it difficult to use false source strategies
