EAGER: Topology Design in Socio-Temporal Evolving Wireless Networks

无线网络经常随着时间的推移而发展：如果一些节点出现、消失或移动，拓扑结构就会发生变化。这种时域动态在协议设计中经常被忽略，或者简单地用纯随机性来建模，比如众所周知的随机行走迁移模型。然而，在真实的无线网络中，节点的移动性和拓扑演化在很大程度上取决于网络和网络参与者的社会特征和时间特征。在这种社会时间进化的无线网络中，由于时变结构、长延迟和缺乏连续连接，为移动自组织网络和延迟容忍网络设计的传统通信协议效率低下。为了解决这一问题，本项目寻求对社会时间演进无线网络和此类网络的拓扑控制协议进行新的探索性研究，具体而言，：(1)通过使用现实生活中的无线网络跟踪数据来分析和模拟演进无线网络的社会时间动态；(2)基于这些社会时间模型设计高效的拓扑控制协议。预期结果包括新的社会时间模型和新的拓扑控制协议，可以支持许多新的民用和军事应用。该项目的成功提供了对时变无线网络的社会和时间特性的深刻理解，并加强了网络科学与社会科学之间的跨学科研究。研究结果将纳入联网课程，并通过会议/期刊出版物广泛传播。

Wireless networks often evolve over time: changes of topology can occur if some nodes appear, disappear, or move around. Such dynamics over time domain are often ignored in protocol design or simply modeled by pure randomness such as in the well-known random walk mobility model. However, in real wireless networks, the node mobility and topology evolution depend heavily on both social and temporal characteristics of the network and network participants. In such socio-temporal evolving wireless networks, traditional communication protocols designed for mobile ad hoc networks and delay tolerant networks are inefficient due to time-varying structures, long delays, and the lack of continuous connectivity. To address this problems, this project seeks a new exploratory study of socio-temporal evolving wireless networks and topology control protocols for such networks, specifically, to (1) analyze and model socio-temporal dynamics of evolving wireless networks by using real-life wireless networking tracing data; (2) design efficient topology control protocols based on these socio-temporal models. The expected results include new socio-temporal models and novel topology control protocols, which can support many new civilian and military applications. The success of this project provides a deep understanding of both social and temporal properties of time-evolving wireless networks and enhances the interdisciplinary research between network science and social science. The research results will be incorporated into networking courses and widely disseminated through conference/journal publications.
