NeTS: Small : Collaborative Research: Harnessing Network Coding Gains in Multi-Rate Wireless Networks

网络编码通过减少总的传输次数来增加无线网络的容量。然而，在实践中，在实现网络编码的收益方面仍然存在许多挑战。特别是网络编码和传输速率控制之间的相互作用还没有仔细研究的日期.虽然在更高的速率传输有利于容量的增加，他们可以减少偷听的可能性，一个关键的要求，网络编码.该建议认为传输速率控制和网络编码的问题，在一个整体的方式.一个框架，检查使用网络编码和多个transmissionrates之间的相互依赖关系，相对于各种功能跨越链路和路由层，被developed.The以下任务正在进行：（i）设计一个网络编码感知传输速率控制模块，允许节点在高比特率传输，而在同一时间促进网络编码。(ii)在链路层和路由层设计一组功能，在应用网络编码和控制干扰和网络拥塞之间提供最佳权衡。（iii）在无线测试床上实现并广泛评估将我们所有功能模块结合在一起的统一框架。学科课程，连接物理和更高层次。

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.
