NeTS-ProWiN: Cognitive Radios for Open Access to SpectrumAward 0434854Narayan Mandayam, RutgersAbstractSpectrum regulation has traditionally been driven by improvements in technology, from improved filters to the sophisticated logic and radio techniques that created the cellular revolution. More recently, however, a new paradigm has emerged in which regulation has driven technology. A modest regulatory experiment in "open spectrum" that began in the ISM bands has spawned an impressive variety of important technologies and innovative uses, from cordless phones and wireless LANs to meter readers and home entertainment products. Since these systems must adapt to a wide variety of unpredictable conditions, the emerging technologies called "cognitive radio" offer significant potential benefits in system capacity and service quality.This investigation begins with the forward-looking assumption that a perfect cognitive radio exists and can configure itself to any transceiver type. Under this assumption, a number of exemplary cognitive strategies are studied to identify the approaches that offer the greatest benefit at the least "cost". These strategies include: (1) discovery of available spectrum, (2) information to support efficient operation, (3) negotiation in situations of conflict, (4) coding for efficient sharing, and (5) domination in situations of conflict. Because these strategies are technologically diverse, their costs are measured against the common metrics of hardware and protocol complexity.This work is carried out using a combination of fundamental analysis, computer simulation and physical emulation using testbeds developed at WINLAB. The results will identify the potential benefits and costs of a diverse set of design strategies, and will be disseminated via a workshop for practitioners in the field.

NetTS-ProWiN：认知无线电开放获取频谱奖0434854 Narayan Mandayam，罗格斯大学摘要频谱监管传统上是由技术进步驱动的，从改进的滤波器到创造蜂窝革命的复杂逻辑和无线电技术。 然而，最近出现了一种新的范式，即监管驱动技术。 从ISM频段开始的“开放频谱”的适度监管实验催生了各种令人印象深刻的重要技术和创新用途，从无绳电话和无线局域网到抄表器和家庭娱乐产品。 由于这些系统必须适应各种各样的不可预测的条件下，新兴的技术称为“认知无线电”提供了显着的潜在好处，在系统容量和服务quality.This调查开始的前瞻性假设，一个完美的认知无线电存在，可以配置自己的任何收发器类型。 在此假设下，一些示范性的认知策略进行了研究，以确定的方法，提供最大的好处在最小的“成本”。 这些战略包括：（1）可用频谱的发现，（2）支持有效操作的信息，（3）冲突情况下的协商，（4）用于有效共享的编码，以及（5）冲突情况下的支配。 由于这些策略在技术上是不同的，他们的成本是衡量对硬件和协议的复杂性的共同metrics。这项工作是使用的基本分析，计算机模拟和物理仿真的组合，使用在WINLAB开发的测试床进行。 评估结果将确定一套不同设计战略的潜在效益和成本，并将通过为实地从业人员举办的讲习班加以传播。
