CAREER: On-the-fly Protocols for Data Dissemination in Wireless Mesh Networks

随着电视频道广播等实时多媒体业务需求的不断增长，以及P2P、视频点播、软件下载等应用对快速下载的要求，接入网设计需要将点对多点、多点对点流量作为头等公民进行高效运营。本计划的高阶目标是在实际时变通道上设计网路协议，以支援无线网状网路中的资料散播。这些网络的特点是无线主干网，而不是连接当今无线接入点的主要有线主干网。本研究基于动态计算的新范式，其中使用最新数据驱动的通道测量来利用通道的时变来增强性能。这项研究将支持新兴的富媒体应用，这将导致网状网络的大规模部署，以提供无处不在的多媒体丰富服务。它将对包括网状网络、无线局域网和ad-hoc网络在内的几个活跃研究领域产生切实的影响。积极推进大学生、妇女和少数民族学生的教育、培训和学习。

With increasing demand for real-time multimedia services such as TV channel broadcasting, and fast download requirements by applications such as P2P, video-on-demand, and software downloads, the access network design needs to treat point-to-multipoint and multipoint-to-point traffic as first class citizens for efficient operation. The high level objective of this project is to design networking protocols over realistic time-varying channels for supporting data dissemination in wireless mesh-networks. These networks are characterized by wireless backbones as opposed to the dominant wired backbones connecting today's wireless access-points. This research is based on the novel paradigm of on-the-fly computation, where recent data-driven channel measurements are used to exploit time-variance of channels for enhanced performance. This research will enable support for emerging media-rich applications that will result in the wide-scale deployment of mesh-networks to provide ubiquitous multi-media enriched services. It will make tangible impacts to several active research areas including mesh-networks, wireless local area networks, and ad-hoc networks. To promote education, training and learning, this effort will actively involve undergraduates, women and minority students.
