Privacy protection added routing method in opportunity network

Abstract

The invention discloses a privacy protection added routing method in an opportunity network. The method comprises the steps of initializing nodes in the opportunity network, wherein each node comprises node privacy information comprising a first actual vector used for storing friend nodes and a second actual vector used for storing utility values; using a Blond filter to perform fuzzy treatment onthe first actual vector and the second actual vector, and acquiring a first mapping vector and a second mapping vector; allowing the current node carrying a message to roam in the opportunity network, so as to detect whether a meeting node exists in the opportunity network; if the meeting node exists, judging whether the meeting node is a target node; if the meeting node is not the target node, determining whether the meeting node is the next hop node of the current node based on the first mapping vector and the second mapping vector of the meeting node; and if the meeting node is the next hop node, sending the message to the meeting node. According to the method, the purpose of protecting the privacy information of the node is achieved, and a success rate of message transmission is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a routing method adding privacy protection in an opportunistic network. Background technique [0002] With the rapid popularization and development of smart phones, the research and development of opportunistic networks are greatly promoted. An opportunistic network is a self-organizing network that does not require a complete path between the source node and the destination node, and uses the encounter opportunities brought about by node movement to realize network communication. Due to the lack of fixed infrastructure in opportunistic networks, it is necessary to rely on encounters between nodes to assist forwarding to achieve communication purposes. How to select the next hop node in an opportunistic network is very important to reduce the message delay rate and network load, and to improve the success rate of message transmission. The commonly used routing protocol i...
