Source position privacy protection method based on three-stage routing in wireless sensor network

Abstract

The invention aims at providing a source position privacy protection method based on three-stage routing in a wireless sensor network. The source position privacy protection method aims at enabling data packets to be subjected to the three-stage routing and to be sent to a base station, avoiding reverse tracing of hunters through random routing of the data packets and achieving source position privacy protection. The three-stage routing includes 1 oriented random routing, 2 annulus h-hop routing and 3 shortest-path routing. Local orientation randomness of a routing path is achieved at very low additional energy consumption cost through the oriented random routing at the first stage, and omnibearing randomness of the routing path is achieved at lower additional energy consumption cost through the annulus h-hop routing at the second stage. According to the scheme, an energy consumption and safety considered optimization method is provided on the premise that the large coverage range of the wireless sensor network in a field is considered. The source position privacy protection method is simple, flexible and easy to achieve and can ensure that a source position has very high privacy protection only by consuming low additional energy consumption cost.

Problems solved by technology

The source location privacy protection technology against global attacks is not practical, because the wireless sensor network used to monitor the wild environment usually covers a large area, and it is not easy for attackers to perform global wireless signal detection on a large-scale wireless sensor network , In addition, the cost of the strategy of allowing a large number of nodes to actively send deceptive data packets adopted by this technology is too high, which will not only shorten the life cycle of the wireless sensor network, but also affect the efficiency of the monitoring system, which is not suitable for wireless sensor network resources. limited features
