NeTS - ProWin: Flexible MAC Protocols for Configurable RadiosJean Walrand, UC BerkeleyAward 0435478AbstractWireless devices are proliferating and have widely different data rate, communication range, and power requirements. Currently, such devices use incompatible communication protocols, which limits their connectivity and restricts the set of applications. We are designing a flexible family of protocols that enables vastly different devices to communicate while preserving their individual requirements. The protocols use an OFDM physical layer. Faster protocols use more parallel channels in parallel. To enable large network utilizations, the devices transmit on pseudo-orthogonal sequences of multiple channels. The protocols select the sequences and perform the necessary rendezvous functions. We use simulations to evaluate the characteristics of the protocols and guide the selection of design parameters. The protocols developed in this project enable very different wireless devices to communicate. They result in backward-compatible systems and should spark the development of new applications that exploit these new communication capabilities. The expected result of the project is a new family of MAC communication protocols validated through extensive simulations. These protocols can be implemented with configurable OFDM radios currently being designed by the industry.

NetTS- ProWin：可配置无线电的灵活MAC协议Jean Walrand，UC Berkeley Award 0435478摘要无线设备正在激增，并且具有广泛不同的数据速率、通信范围和功率要求。 目前，这种设备使用不兼容的通信协议，这限制了它们的连接性并限制了应用程序的集合。 我们正在设计一个灵活的协议系列，使不同的设备能够在保持各自需求的同时进行通信。 这些协议使用OFDM物理层。 更快的协议并行使用更多的并行通道。 为了实现大的网络利用率，设备在多个信道的伪正交序列上进行传输。 协议选择序列并执行必要的会合功能。 我们使用模拟来评估协议的特性，并指导设计参数的选择。 在这个项目中开发的协议使非常不同的无线设备进行通信。 它们导致了向后兼容的系统，并应该激发开发利用这些新通信功能的新应用程序。 该项目的预期结果是通过广泛的模拟验证了一系列新的MAC通信协议。 这些协议可以用当前由业界设计的可配置OFDM无线电来实现。
