摘　　要：在社会感知网络(social aware networking,SAN)中,由于节点资源能量限制和服务能力不足,部分中间节点会出现自私行为。另外,为了追求高收益或高信誉值,节点之间还会进行共谋谎报信息或篡改数据。因此如何激励自私节点积极参与转发数据和保证数据安全成为当前的研究热点。首先,本文阐述了导致节点出现自私性的因素以及其自私性行为给网络带来的问题。其次,介绍了三种主要的激励策略和由这三种策略形成的组合策略,并阐述了在数据转发中存在的安全问题。最后,根据现存的一些问题总结了未来的研究方向。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 behavior 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 elaborated.Finally,future research directions were summarized based on the existing issues.
