Research on Motivation and Security of Selfish Nodes inSocial Aware Networking
In Social Aware Networking(SAN),due to resource and energy limitations and insufficient service capabilities of nodes in the network,some intermediate nodes may exhibit selfish behaviors.In addition,in order to pursue high returns or high reputation,nodes may collude with each other to falsely report information or tamper with data.Hencehow to stimulate selfish nodes to actively take part in forwarding data and ensure data security has become a current research hotspot.Firstly,this paper described the factors that cause nodes to appear selfish and the problems that their selfish be-havior brings to the network.Secondly,three main incentive strategies and the combination strategies formed by these three strategies were introduced and the security issues in data forwarding were elabo-rated.Finally,future research directions were summarized based on the existing issues.
