Method for acquiring node trust value based on detection route in energy harvesting wireless sensor network to avoid black hole node attack

Abstract

The invention discloses a method for acquiring a node trust value based on a detection route in an energy harvesting wireless sensor network to avoid black hole node attack. In the energy harvesting wireless sensor network, the energy of the nodes, in addition to meeting the data routing energy required for transmitting data packets among the nodes, remains. According to the method, the residual energy of the nodes can be fully utilized, and the detection route is established among the nodes in the network. Establishment of the detection route comprises sending a detection packet and receiving a feedback packet, and because a black hole node cannot correctly distinguish a data packet and the detection packet, malicious packet loss behaviors occur in the transmission process of the detection route, and position information of the detection route is exposed. According to the position information of the black hole node acquired by the detection route, the credibility of the malicious node is reduced, so that the node with higher credibility is selected to transmit the data packet in the transmission process of the next-hop data route. Through calculation of the node trust value, black hole nodes can be effectively avoided, and the data routing success rate of the network is improved. The residual energy of the nodes is fully utilized, and the energy utilization rate of the network is improved.
