具有社会特性的无线多跳网络以协作通信方式支持用户间的数据交互，已成为学术界的研究热点。由于其网络拓扑多变性、节点有社会性，用户需求多样性，需优化使用有限的网络资源，在提高吞吐量的同时满足用户的社会需求。单一的协作通信方式已无法满足上述的通信传输需求，因此在具有社会特性的无线多跳网络中进行异构协作通信方式融合的研究具有重要意义。本项目主要研究如何将节点的社会属性、网络通信条件、节点自身传输能力进行综合评估，再根据不同协作通信方式的适用条件和性能增益，自适应地选择最佳中继节点和协作通信方式，并通过有效地调度实现节点间的协作通信。本课题属于前沿探索性的应用基础研究，所涉及的关键问题是当前学术界的新问题，研究内容包括：基于关联度的社区辅助图模型构建、面向节点社会特性的中继节点选择机制研究、支持协作通信方式自适应选择的调度机制研究。

In wireless social-attribute multihop networks, users' information exchanges are completed by cooperative communications, which has become a hot research topic. Due to the network characteristics including variability of network topology, sociability of node and diversity of users' requirements, it is imperative to optimize spectrum utilization to improve network throughput meanwhile satisfying users' social needs. Single cooperative communication method may not be able to fulfill the above transmission requirements. Therefore, it is very meaningful to study the integration of heterogeneous cooperative communication methods in social-attribute multihop networks. This project mainly studies how to comprehensively evaluate each node's sociability and transmitting ability, and network conditions. Meanwhile, the implementation conditions of different cooperative communication methods and the network performance improvement contributed by them are analyzed. Based on the above evaluation and analysis, each node adaptively selects the optimal relay and the corresponding cooperative communication method, and performs information exchange with other nodes by effective scheduling. This project belongs to leading-edge application research, and the key problems involved are the newly emerging problems in the literature. The research contents include: establishment of social association based community graph, research on social-oriented relay selection schemes, and research on scheduling schemes that support adaptive selection of cooperative communication methods.
