Networking and Control Issues for Mobile Radio Communications Systems

拟议研究的总体目标是为移动网络开发合适的网络概念，以及允许系统性能的理论预测和参数权衡检查的分析模型和方法。特别令人感兴趣的是提供智能特性的技术，它们使移动网络能够通过调整和适应通信环境的变化来保持性能水平。在蜂窝和非蜂窝配置中，将研究由于流量负载、干扰和拓扑变化而导致的通信资源的动态控制、分配和再分配。需要调查的领域包括：管理通信平台移交的技术；利用空间宏观多样性特征；以及通信资产的动态控制和分配——包括通道和网关的借用和共享。实现这一目标的程序可能包括中央控制和分布式控制的混合。将考虑这些技术在各种情况下的适当性。分析建模和计算机模拟将提供主要的基础。预计这项调查的结果将设计出新的技术，以便改进与广大地理区域内大量移动平台的通信。此外，分析模型和方法将为理解、建模和设计移动通信网络提供一个增强的基础。

The overall objective of the proposed research is to develop suitable networking concepts for mobile networks, along with analytical models and methodology that permit both theoretical prediction of system performance and examination of parameter tradeoffs. Of particular interest are techniques that provide intelligent features in the sense that they enable mobile networks to maintain performance levels by adjusting and adapting to changes in the communications environment. Dynamic control, assignment, and reallocation of communication resources due to changes in traffic loading, interference, and topology will be investigated for cellular and non-cellular configurations. Areas to be investigated include: techniques for managing hand-offs of communicating platforms; use of spatial macro-diversity features; and dynamic control and assignment of communications assets - including both borrowing and sharing of channels and gateways. Procedures to accomplish this may involve mixtures of central and distributed control. Appropriateness of the techniques for various settings will be considered. Analytical modeling and computer simulation will provide the primary underlying bases. It is expected that as a result of this investigation new techniques will be devised that will allow improved communications with large numbers of mobile platforms over wide geographical areas. In addition, the analytical models and approach will provide tan enhanced foundation for understanding, modeling, and designing mobile communications networks.
