Description

technical field [0001] The invention relates to the field of secure communication of wireless sensor networks, and is mainly used in target tracking, biological medical treatment, wild animal monitoring and other application occasions where wireless sensor networks involve the protection of monitoring object security communication, specifically a source location of wireless sensor networks based on irregular rings Secure Routing Design Methodology. Background technique [0002] As the main component of IoT (Internet of Things, IoT) applications, wireless sensor networks have been widely used in target tracking, smart medical care, wildlife monitoring, smart agriculture and other fields. When wireless sensor networks are deployed in harsh wild environments or uninhabited areas, due to the particularity of their own communication mechanisms and the limitation of node resources, the security issues of sensor networks are particularly prominent. The lack of an effective securit...

Problems solved by technology

Ozturk designed a security mechanism to protect source location privacy, a source location privacy security scheme based on random walk phantom routing; Li et al. proposed the RSIN scheme, which mainly has two stages: the first stage, randomly select an intermediate node, the source node forwards the data packet to the intermediate node, and in the second stage, the intermediate node forwards the data packet to the ring node, the data packet is forwarded on the ring, and then sent to the base station node. In this scheme, the ring node consumes more energy than other nodes energy, reducing the life cycle of the network; Tan et al. proposed the path extension method PEM scheme, which uses dynamic pseudo-sources to induce attackers to stay away from the real source node. In this scheme, when the source node is close to the base station node, the efficiency of protecting the source node is relatively high. Low, the more pseudo-source nodes in this scheme, the greater the energy consumption; Raja proposed the SLP-R scheme, which is divided into three stages: the first stage is reverse random walk, the source node sends the data packet to the direction away from the sink node Randomly forward a certain number of hops, the second stage is the same as deep routing, the node forwards data to the node with the same hop number (the same hop value from the base station), and the third stage node forwards the data packet to the sink node. In this scheme, the path diversity is limited Limitation, the energy consumption of nodes in the network is unevenly distributed
