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

随着电视频道播放等实时多媒体业务需求的增加，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到多点和多点到点的业务视为一等公民，以实现高效运营。该项目的高级目标是在现实的时变信道上设计网络协议，以支持无线Mesh网络中的数据传播。这些网络的特点是无线主干，而不是连接当今无线接入点的主要有线主干。这项研究基于动态计算的新范例，其中使用最新的数据驱动的通道测量来利用通道的时变来提高性能。这项研究将支持新兴的富媒体应用，从而导致网状网络的广泛部署，以提供无处不在的多媒体丰富服务。它将对几个活跃的研究领域产生切实的影响，包括网状网、无线局域网和自组织网络。为了促进教育、培训和学习，这一努力将积极涉及本科生、妇女和少数民族学生。

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.
