【摘要】：随着科技的进步与发展,移动联网设备的全面普及,人们对网络的快速化、稳定性和覆盖率的要求越来越高。机会网络作为未来多网络融合的补充,能够在恶劣的环境下工作,对网络的优化起到重要作用。机会网络中现有的大多数路由策略都是建立在节点间完全合作的基础上,然而,由于节点资源有限以及各自的偏好性等,中继节点很容易表现出自私的一面,诸如拒绝参加数据转发、丢弃转发信息等。因此,如何降低节点自私行为对网络性能的影响已然成为现在研究的热点。首先介绍了自私节点的产生、检测以及其对网络性能的影响,分析了节点自私行为的研究对机会网络的重要性。然后,阐述了现有的三类激励方案,对每类方案中典型的激励策略进行详细介绍,并分析了每个策略的优缺点。最后,对三类方案进行了比较,并对未来的研究方向提出了建议和展望。
[Abstract]:With the progress and development of science and technology and the popularization of mobile networking devices, the requirements of network speed, stability and coverage are becoming higher and higher.As a supplement of multi-network convergence in the future, opportunistic networks can work in harsh environment and play an important role in network optimization.Most of the existing routing strategies in opportunistic networks are based on the complete cooperation between nodes. However, due to the limited resources of nodes and their preferences, relay nodes tend to show selfishness.Such as refusing to participate in data forwarding, discarding forwarding information, and so on.Therefore, how to reduce the impact of node selfishness on network performance has become a hot topic.Firstly, the generation and detection of selfish nodes and their effects on network performance are introduced, and the importance of the study of selfishness behavior to opportunistic networks is analyzed.Then, three kinds of incentive schemes are introduced, and the typical incentive strategies are introduced in detail, and the advantages and disadvantages of each strategy are analyzed.Finally, three kinds of schemes are compared, and suggestions and prospects for future research are put forward.
