Abstract

The invention discloses a method for protecting source node location privacy in a wireless sensor network based on phantom routing. Firstly, base station nodes perform network initialization in a beacon flooding manner, so that the nodes can generate respective neighbour lists; secondly, a source node calculates a proper expected phantom source node location through network partition; furthermore,a data packet is sent to the location according to a routing algorithm, and finally arrives at a phantom source node; and finally, the phantom source node transmits the data packet to the base station nodes in a manner of randomly selecting a neighbour node. By means of the method disclosed by the invention, the fact that the phantom source node is enough far away from a real source node can be ensured; furthermore, the path of the data packet from the source node to a base station every time has the randomness; furthermore, the paths of adjacent data packets are not repetitive; therefore, the source node can be ensured to have the enough security data transmission time; and the location privacy of the source node is protected.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor network communication support, and in particular relates to a phantom routing-based privacy protection method for a source node location of a wireless sensor network. Background technique [0002] Wireless sensor network is a kind of wireless multi-hop self-organizing network. Because of its flexible network setting and strong environmental adaptability, it is widely deployed in harsh environments such as wild animal habitats or military battlefields. Due to the openness of wireless sensor networks, it is easy for attackers to determine the location of source nodes through traffic analysis and other means, thus threatening the safety of protected organisms or our soldiers. Therefore, research on privacy protection schemes for source node locations in wireless sensor networks has attracted people's attention. In the past few years, people have proposed a variety of source node location pri...
