中文摘要: 分布式无线通信网络是4G无线网络架构的重要组成部分。多址接入协议(即MAC协议)设计的好坏决定了整个分布式无线网络的性能。为了同时有效解决好MAC协议设计所面临的"链路不可靠问题"和"链路间干扰问题",项目提出了将"协作中继"和"信道预约"有机结合在一起的思想,进而为构建高性能分布式MAC协议开辟了新的研究途径。为了实现这一MAC协议的设计思想,项目进一步提出了"预约协作链路"的概念。项目研究的基本出发点是:深入研究预约协作链路的建模分析方法及其有效通过率性能,并以此为基础研究构建以预约协作链路为基本接入单元的高性能复合型MAC协议的方法。主要研究内容包括:预约协作链路的建模分析与性能优化;分布式预约协作链路的调度策略;复合型MAC协议总体框架的设计与优化。分析由预约协作链路所组成的分布式无线网络的网络通过率,并据此提出优化网络通过率的方法,是本项目拟解决的关键科学问题。

英文摘要: Distributed wireless networks are important building blocks for 4G wireless networking architecture. Performance of Medium Access Control protocols, i.e. MAC protocols, determines the final performance of distributed wireless networks. In order to effectively solve both the problem of "the stability of a wireless communication link" and the problem of "the interference between different wireless communication links", a design idea of combining "cooperative relay" and "channel reservation" is proposed in the project, which opens up a new way of designing high performance distributed MAC protocols. Furthermore, in order to achieve the design idea, a concept, i.e. "Reserved Cooperative Link", is proposed. The basic starting point for the researches in the project is to study in depth the modeling and the effective throughput of a single reserved cooperative link, and find out ways of designing high performance distributed MAC protocols by using each single reserved cooperative link as the fundamental access unit. Researches in this project can be summurized below: studies on modeling, analysis, and performance optimization of a single reserved cooperative link; studies on distributed link scheduling schemes for multiple reserved cooperative links; and studies on the design and optimization of the framework for hyb
