Exploration and utilization of broadcasting nature of multi-hop wireless networks

多跳无线网络研究一种无线数据通信方案，其中消息在到达目的地之前在无线链路上被转发多次。 多跳无线网络是互联网的强大扩展，将使其成为真正无处不在的基础设施。 自20世纪70年代开创性的分组无线电网络以来，对这种联网范例的研究已经取得了丰硕成果。 不仅开发了不同的使能技术，而且这些技术也开始无缝地集成到互联网中。 实现利用这种网络的灵活性和高网络运营效率的切实目标即将到来。 然而，我们不应该满足于多跳无线网络将与互联网“一样好”的事实。事实上，对多跳无线的研究主要集中在解决网络框架中出现的问题，这些问题或多或少是互联网的偏差或附加组件。 互联网数据传输的最基本公理，即，直到最近，在具有多个基本上点对点链路的一组节点之间的分组转发一直是完整的。 这将通过认识和接受多跳无线网络的无线通信信道的广播性质来改变。 事实上，在这种情况下，无线链路是一个有限范围的广播和多路访问信道，这是一个比互联网中的点对点信道更通用和更强大的模型。 离开实践，禁锢互联网，才是超越互联网的途径，要比互联网巨人看得更远，就要站到他的肩膀上。 建议的研究的长期目标是调查的多跳无线网络的固有特性，以克服这种网络的缺点，从互联网上翻译的操作方法，并充分发挥其潜力。 它将促进最先进的数据通信，使我们更接近无处不在的计算和信息自动化的最终目标。

Multi-hop wireless networking studies a wireless data communcation scheme, where messages are forwarded multiple times over wireless links before reaching the destination for delivery. Multi-hop wireless networks are a powerful extension to the Internet that will allow it to be a truly ubiquitous infrastructure. Since the pioneering Packet Radio Network in the 1970's, research on such a networking paradigm has been fruitful. Not only have different enabling technologies been developed, they are also starting to be integrated to the Internet seamlessly. Achieving the tangible goal of harnessing the flexibility of such networks with high network operation efficiency is on the horizon. However, we should not be contented with the fact that multi-hop wireless networks are to be "as good as" the Internet. In fact, research on multi-hop wireless has been primarily focused on addressing issues emerging from a networking framework which are more or less deviations of or add-ons to the Internet. The most fundamental axiom of the Internet data transportation, i.e., packet forwarding among a group of nodes with multiple essentially point-to-point links, has been intact until recently. This is to be changed by recognizing and embracing the broadcasting nature of wireless communication channels of multi-hop wireless networks. Indeed, a wireless link in this case is a limited-scope broadcasting and multiple-access channel at the same time, which is a much more general and potentially more powerful model than the point-to-point channels in the Internet. Departure from practice and confinement of the Internet is the way to transcend it. To see further than the Internet giant, we must get onto his shoulders. The long term objective of the proposed research is to investigate the inherent properties of multi-hop wireless networks in order to overcome disadvantages of such networks induced by translating operating methods from the Internet and to fully unleash their potentials. It will advance the state-of-the-art data communication, so that we are ever closer to the ultimate goal of ubiquitous computation and information automation.
