ITR: Vertical Protocol Integration In Ad-hoc Wireless Networks

高性能网络的设计、规划、控制和管理需要一种比传统的分层方法更集成的方法，在传统的分层方法中，每一层都是独立于其他层进行设计和优化的。在这项提案中，研究人员提出利用网络协议中的层间依赖性来提高网络性能。特别是，研究人员将重点关注ad-hoc无线网络，其中这些相互依赖性更加明显，网络将通过跨层设计显著受益。主要关注物理层，MAC层和路由/传输层之间的交互。研究人员考虑到的传输参数和检测器结构的详细建模的无线介质的性质，并考虑TDMA（预定）和CDMA媒体访问控制机制。研究人员耦合这些流量和路由分配问题，并进一步考虑如何传输协议与路由选择和带宽allocation. Also相互作用，研究人员解决的作用，网络控制和管理在ad-hoc无线网络，并利用其与上述层的相互作用。最后，研究人员考虑了信号压缩与速率和质量控制的相互作用，并注意到联合协议设计的能耗影响。

Abstract0205330The design, planning, control and management of high performance networks require a much more integrated approach than the conventional layered approach, where each layer is designed and optimized independently from the others. In this proposal the researchers propose to exploit inter-layer dependencies in network protocols for improved network performance. In particular, the researchers will focus on ad-hoc wireless networks, in which these interdependencies are more pronounced and in which the network will benefit significantly by crosslayer designs.The main focus is on the interaction between the physical layer, the MAC layer, and the routing/transport layers. The researchers take into account the nature of the wireless medium by detailed modeling of the transmission parameters and of the detector structure and consider both TDMA(scheduled) and CDMAmedia-accesscontrol mechanisms. The researchers couple these with the flow and route assignment problems and, furthermore, consider how the transport protocol interacts with route selection and bandwidth allocation.In addition, the researchers address the role of network control and management in ad-hoc wireless networks and exploit its interaction with the aforementioned layers. Finally, the researchers consider the interaction of signal compression with rate and quality control and are mindful of the energy consumption repercussions of the joint protocol design.
