Gang Xu, Xinyu Hao, Zhihan Qi, Baoqi Huang · 2023
Recent research on opportunistic network routing protocols has found that the efficiency of message forwarding varies with the selection of next-hop nodes, so it is of great significance to select the appropriate next- hop nodes for message forwarding. This paper proposes a Node Importance Algorithm Based on Social Properties of Nodes (NI). The importance evaluation model is established by using the social attributes of node centrality and relevance, and the importance forwarding algorithm is constructed according to this model. The algorithm first calculates the node importance and selects the node with higher importance as the next hop forwarding node based on this model. The experimental simulation results show that the algorithm can select more appropriate next-hop nodes to complete message forwarding, so as to improve the message delivery rate of the network.
