Abstract

Previous works in cognitive radio networks (CRNs) have shown that cooperation in sensing improves sensing reliability and in turn enhances the network throughput. However, the cooperative behavior is accepted as the default mode of operation, which may not always hold. In this work, we loose this assumption and introduce a cooperative mode of operation conditioned on social relations between Cognitive Radios (CRs). Rather than taking CRs as wireless devices with no context, we associate each CR with its user that has some social relations, e.g. friendship, community, selfishness. Using these relations among CRs, we propose a social-aware cooperative sensing scheme and analyze its effects on sensing performance. We believe that exploiting social metrics assists cooperative sensing in CRNs and a model with social relations embedded will fit better to the next decade's networking paradigm.
认知无线电网络中社会关系对合作感知的影响
认知无线网络(crn)的研究表明,感知中的合作提高了感知可靠性,进而提高了网络吞吐量。然而,合作行为被接受为默认的操作模式,这可能并不总是成立。在这项工作中,我们放弃了这一假设,并引入了一种以认知无线电(CRs)之间的社会关系为条件的合作操作模式。我们不是将CR作为没有上下文的无线设备,而是将每个CR与具有某些社会关系的用户关联起来,例如友谊,社区,自私。利用这些关系,我们提出了一种社会意识的协同感知方案,并分析了其对感知性能的影响。我们认为,利用社会指标有助于crn中的合作感知,嵌入社会关系的模型将更适合下一个十年的网络范式。
