项目摘要

Network coding brings the promise of increased wireless network capacity by decreasing the overall number oftransmissions. In practice however, many challenges remain in realizing the gains from network coding. In particularthe interactions between network coding and transmission rate control have not been carefully studied to date.While transmission at higher rates favor a capacity increase, they can diminish overhearing possibilities, a key requirementof network coding.This proposal considers the problem of transmission rate control and network coding in a holisticway. A framework that examines the interdependencies between the use of network coding and multiple transmissionrates with respect to various functions spanning the link and routing layers, is developed.The following tasks are being undertaken: (i) Design a network-coding aware transmission rate control modulethat allows nodes to transmit at the high bit rates while at the same time facilitating network coding.(ii) Design a set of functions at the link and routing layers that provide the best trade-offs between applyingnetwork coding and controlling interference and network congestion(iii) Implement and extensively evaluate a unified framework combining all of our functional modules on wireless testbeds.The proposed research is tightly knit with new education programs by establishing wireless teachinglaboratories and introduce cross-disciplinary courses that bridge the physical and higher layers.

网络编码通过减少转机数量来增加无线网络容量的承诺。但是，实际上，在实现网络编码的收益方面仍然存在许多挑战。特别是，尚未仔细研究网络编码与传输速率控制之间的相互作用。虽然较高的速率传输有利于增加能力，但它们可能会减少偷听的可能性，这是网络编码的关键要求。该提案认为，在整体通道中的传输速率控制问题和网络编码问题。开发了一个框架，该框架正在开发网络编码和多个传输量相对于跨越链路和路由层的多个功能之间的相互依赖性。正在开发以下任务。在应用网络编码和控制干扰和网络拥塞（III）之间，并广泛评估统一的框架，将我们所有功能模块结合在无线测试床上。拟议的研究是通过建立无线教学课程的新教育计划紧密编织的，并通过建立无线教学课程，并引入跨学科的课程，并引入跨学科和更高层的跨学科课程。
