Energy Efficient Wireless Communication Networking

随着对宽带多媒体无线通信和信息服务需求的增加，无线通信网络中的能量消耗已经成为主要关注点。大多数现有的节能技术不能被应用，因为它们受限于无线传感器网络，其中传感器具有有限的功率和功能，具有非常低的数据业务负载和无（或低）移动性。因此，全球范围内启动了许多研发计划，以开发节能（绿色）无线通信和网络技术。拟议的研究计划旨在研究宽带多媒体移动的通信的能源效率和通信服务质量之间的基本权衡，并开发新的网络解决方案，以更好地兼顾能源效率和服务质量。具体而言，我们将重点关注三个方面：1）根据网络动态的自适应链路控制，使得移动的终端能够在活动模式和休眠模式之间交替，2）端到端信息传递，使得能够进行能量有效的数据业务路由以最小化能量消耗并最大化网络寿命，以及3）网络协作，这将允许某些基站在业务负载较轻的时间和位置被关闭，并且极大地扩展了每个活动基站的服务覆盖区域，以确保连续的服务质量。多样化的服务质量要求、多媒体通信中的数据业务动态性以及随机用户移动性对在不损害服务质量的情况下提高能源效率提出了重大的技术挑战。研究成果预计将产生深远的技术和科学影响，为开发更灵活和实用的节能无线网络算法和协议提供深入的理解和指导，并帮助加拿大建立和加强其在绿色无线网络方面的领导地位。该计划将培养一大批高素质的人才，为他们提供分布式节能资源分配和网络控制方面的宝贵见解和经验，并使他们成为加拿大高科技产业劳动力的专家补充。

With increasing demand for broadband multimedia wireless communication and information services, energy consumption in wireless communication networks has become a major concern. Most existing energy efficient techniques cannot be applied as they are limited for wireless sensor networks, where the sensors have limited power and functionalities with very low data traffic load and no (or low) mobility. As a result, many R&D initiatives have been launched worldwide to develop energy efficient (green) wireless communications and networking technologies. The proposed research program aims to study fundamental tradeoffs between energy efficiency and communication service quality for broadband multimedia mobile communications, and to develop new networking solutions for better compromise between energy efficiency and service quality. In particular, we will focus on three thrusts: 1) adaptive link control according to network dynamics, enabling mobile terminals to alternate between active and sleeping modes, 2) end-to-end information delivery, enabling energy efficient data traffic routing to minimize energy consumption and maximize network lifetime, and 3) network cooperation, which will allow some base stations to be turned off when and where traffic loads are light, and greatly expand the service coverage area of each active base station to ensure continuous service quality. Diverse quality-of-service requirements, data traffic dynamics in multimedia communications, and random user mobility pose significant technical challenges to improve energy efficiency without compromising service quality. The research outcomes are expected to have a profound technological and scientific impact, in providing in-depth understanding and guidelines for developing more flexible and practical energy efficient wireless networking algorithms and protocols, and in helping Canada to establish and reinforce its leadership in green wireless networking. This program will train a large pool of highly qualified personnel, providing them with valuable insights and experiences in distributed energy efficient resource allocation and network control, and enabling them to emerge as expert additions to the Canadian high technology industry labor force.
