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全面的方法，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。在该方案中，研究人员建议利用网络协议中的层间依赖关系来提高网络性能。特别是，研究人员将重点放在ad-hoc无线网络上，在这种网络中，这些相互依赖关系更加明显，并且网络将通过跨层设计获得显著的好处。主要关注的是物理层、MAC层和路由/传输层之间的交互。研究人员通过对传输参数和检测器结构的详细建模来考虑无线介质的性质，并同时考虑TDMA(调度的)和CDMA介质访问控制机制。研究人员将这些问题与流量和路由分配问题相结合，并进一步考虑了传输协议如何与路由选择和带宽分配进行交互。此外，研究人员还讨论了网络控制和管理在自组织无线网络中的作用，并利用其与上述层的交互。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量消耗影响。

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.
