PIS：一种面向社会感知网络的多维路由协议
PIS: A Multi-dimensional Routing Protocol for Socially-aware Networking
摘要：
社会感知网络是一种新兴的模式，间歇连接的网络组成的移动用户的社会关系和特点。在这种情况下，人类是移动设备的主要携带者。因此，可以利用它们的连接，社交功能和行为来提高数据转发协议的性能。在本文中，我们首先探讨了三个社会特征，即物理接近，用户的兴趣和社会关系对用户的日常生活的影响。然后，我们提出了一个多维的路由协议，称为接近感兴趣的社会（PIS）协议，其中三个不同的社会层面被集成到一个统一的距离函数，以选择最佳的中间数据载体。PIS协议利用时隙管理机制来发现用户在一天中不同时间段的运动相似性。我们使用SIGCOM09和INFOCOM06数据集比较PIS与Epidemic、PROPHET和SimBet路由协议的性能。实验结果表明，PIS协议具有最高的数据传输率和较低的通信开销，优于其他基准路由协议。
英文摘要：
Socially-aware networking is an emerging paradigm for intermittently connected networks consisting of mobile users with social relationships and characteristics. In this setting, humans are the main carriers of mobile devices. Hence, their connections, social features, and behaviors can be exploited to improve the performance of data forwarding protocols. In this paper, we first explore the impact of three social features, namely physical proximity, user interests, and social relationship on users' daily routines. Then, we propose a multi-dimensional routing protocol called Proximity-Interest-Social (PIS) protocol in which the three different social dimensions are integrated into a unified distance function in order to select optimal intermediate data carriers. PIS protocol utilizes a time slot management mechanism to discover users' movement similarities in different time periods during a day. We compare the performance of PIS to Epidemic, PROPHET, and SimBet routing protocols using SIGCOMM09 and INFOCOM06 data sets. The experiment results show that PIS outperforms other benchmark routing protocols with the highest data delivery ratio with a low communication overhead.
