NeTS-ProWiN: Spectrum-Agile Wireless Available Networking (SWAN)

Jose Garcia-Luna-Aceves， University of California-Santa CruzAward 0435522abstract迄今为止演示的自组织网络在预先分配的频谱部分上运行，这限制了它们的连接性和可用频谱的使用效率。自组织网络被假定为独立于Internet工作，并且仅通过几个接入点连接到Internet。此外，无线路由器被认为是不同于因特网路由器的，今天的自组织网络中的路由是独立于频谱管理或有线链路的可用性的。SWAN（频谱敏捷无线可用网络）项目解决了上述限制，使无线频谱利用比目前可能的方式更有效，并使无线链路成为互联网的组成部分。SWAN的预期结果包括：(a)无线可用网络：SWAN将开发一种架构和协议，将自组织网络的概念转化为无线可用网络，这样互联网路由器就可以机会地使用无线电链路，就像今天路由器使用有线链路一样。(b)可用频谱启发式统计复用（SMASH）： SWAN将根据信息流统计开发用于动态共享可用频谱的算法、协议和礼仪。通过这种方式，路由器以分布式方式确定它们可以使用的频谱的哪一部分。(c)基于策略的路由：SWAN将为无线网络开发第一个基于策略的路由协议，路由器将根据管理、服务质量和频谱利用策略来管理互联网有线和无线部分的拓扑结构和路径。

NeTS-ProWiN: Spectrum-Agile Wireless Available Networking (SWAN)Jose Garcia-Luna-Aceves, University of California-Santa CruzAward 0435522AbstractAd hoc networks demonstrated to date operate on pre-assigned portions of the spectrum, which limits their connectivity and the efficiency with which the available spectrum is used. Ad hoc networks are assumed to work independently of the Internet and attach to it only through a few access points. Furthermore, wireless routers are considered to be different from Internet routers, and routing in ad hoc networks today is independent of spectrum management or the availability of wired links.The SWAN (Spectrum-Agile Wireless Available Networking) project addresses the above limitations by enabling wireless spectrum utilization in far more efficient ways than it is possible today, and by making wireless links an integral part of the Internet. The expected results in SWAN include:(a) Wireless Available Networking: SWAN will develop an architecture and protocols that transform the concept of ad hoc networking into wireless available networking, such that Internet routers use radio links opportunistically, in much the same way as wired links are used today by routers.(b) SMASH (Statistical Multiplexing of Available Spectrum Heuristics): SWAN will develop algorithms, protocols, and etiquettes for the dynamic sharing of the available spectrum based on the statistics of information flows. This way, routers determine in a distributed fashion which portion of the spectrum they can use.(c) Policy-based Routing: SWAN will develop the first policy-based routing protocols for wireless enabled networks, with which routers manage the topology and paths of wired and wireless portions of the Internet based on administrative, quality-of-service, and spectrum-utilization policies.
