无线网络的未来将是异构的,利用具有各种各样的能力和约束的各种空中接口。它将通过一个了解人们的存在和背景并对他们的需求敏感的数字环境来增强人们的权能。不幸的是,今天的空中接口仅仅是共存的,并且在使它们合作以提供鲁棒、安全和可扩展的网络方面几乎没有实现。两个主要问题阻碍了这种网络的成功部署:资源的限制和脆弱性的鲁棒性和异构设备之间的通信的安全性。这些问题的复杂性和关键性随着网络的规模和组成它的设备的多样性而增加。本项目研究跨层通信协议和资源管理策略的设计和原型,以适应环境的变化(流量特性,信道质量,拓扑和移动性,能量和对手攻击)。该方法是基于理论概念,如广义冲突图,线性规划,编码和信息理论,但也启发式技术的跨层资源成本度量,自适应物理层,竞争感知路由。该项目考虑了一种跨层的方法来对抗对手。该项目的成果有两个方面:用于强大,可扩展和安全通信的跨层算法和协议,以及包括模拟器和原型在内的评估工具。开发用于“环境智能”的创新网络技术将是发展一个充满活力、包容、安全和富有成效的社会的重要有利因素,在这个社会中,获得服务和信息的机会是廉价、透明的,最重要的是安全的。
英文摘要
The future of wireless networking will be heterogeneous, making use of various air interfaces with a wide variety of capabilities and constraints. It will empower people through a digital environment that is aware of their presence and context and sensitive to their needs. Unfortunately, today's air interfaces merely co-exist, and very little has been achieved in making them co-operate to provide robust, secure, and scalable networks. Two main issues hinder the successful deployment of such networks: limitation of resources and vulnerability of robustness and security of communications among heterogeneous devices. The complexity and criticality of these issues increase with the size of the network and the variety of the devices that compose it. This project investigates the design and prototyping of cross-layer communication protocols and resource-management strategies to accommodate variations in the environment (traffic characteristics, channel quality, topology and mobility, energy, and adversary attacks). The approach is based on theoretical concepts such as generalized conflict-graphs, linear programming, coding and information theory, but also heuristic techniques for cross-layer resources cost-metrics, adaptive physical-layer, and contention-aware routing. The project considers a cross-layer approach to robustness against adversaries. The outcomes of the project are two fold: cross-layer algorithms and protocols for robust, scalable and secure communication, and evaluation tools including simulators and prototypes. The development of an innovative networking technology for "ambient intelligence" will be a significant enabling factor in the development of a vibrant, inclusive, safe, and productive society where access to services and information is cheap, transparent, and, most importantly, secure.
