This project develops a theory for understanding the requirements for control overheads in wireless networks and mechanisms for reducing the amount of these overheads. Network control mechanisms, such as scheduling, routing, and flow control, ensure effective data transport in a communication network, but also require the exchange of network state information, such as channel conditions and queue-length information, which amounts to 'control overhead'. The project investigates the tradeoffs between the rate of sending such control information, and the ability to effectively control the network in terms of performance metrics such as throughput, stability, delay and network utility. The project takes a two-pronged approach: First, a rate-distortion framework is being developed for understanding the impact of degraded network state information on network performance. Second, mechanisms are being developed for reducing the amount of control overhead and the impact of these mechanisms on network performance is being investigated. The project develops a fundamental understanding of the requirements for protocol overhead, which will lead to more efficient network control policies, with reduced overheads. Such improvements will have a significant impact on network performance, especially in wireless networks, which experience large overheads due to protocol inefficiencies. The results will be widely disseminated through publication in conferences, journals and the web to help advance the wireless networking field. The broader impacts include training of graduate and undergraduate students and technology transfer to industry and government laboratories.

本项目开发了一种理论，用于理解无线网络中对控制开销的需求以及减少这些开销的机制。网络控制机制，如调度、路由和流量控制，确保通信网络中有效的数据传输，但也需要交换网络状态信息，如通道条件和队列长度信息，这相当于“控制开销”。该项目研究了发送此类控制信息的速率与根据吞吐量、稳定性、延迟和网络效用等性能指标有效控制网络的能力之间的权衡。该项目采用双管齐下的方法：首先，正在开发一个速率失真框架，以了解降级的网络状态信息对网络性能的影响。其次，正在开发减少控制开销的机制，并正在研究这些机制对网络性能的影响。该项目开发了对协议开销需求的基本理解，这将导致更有效的网络控制策略，同时减少开销。这种改进将对网络性能产生重大影响，特别是在无线网络中，由于协议效率低下，无线网络的开销很大。研究结果将在会议、期刊和网络上广泛传播，以推动无线网络领域的发展。更广泛的影响包括培训研究生和本科生以及向工业和政府实验室转移技术。
