The use of wireless technology has the potential to significantly reduce the cost and enhance the growth of broadband data access, which is currently dominated by the cost of installation and maintenance of wired networks. A significant challenge in wireless networks is the issue of cross-layer design, which this research addresses by modeling broadband wireless networks as a complex system of interacting economies with two parts, wireless bandwidth (local), and the network core link-capacities (end-to-end). Media access control (MAC) provides a bandwidth multiplexing scheme, while at the transport layer, congestion/rate control determine the demand, hence the buffer and capacity allocation. In other words, the optimal design of broadband wireless networks can be viewed as the problem of scalable yet optimal utilization/sharing of various resources among autonomous users. Economists have been studying similar problems in various contexts such as air pollution, traffic management, etc. It is known, for example, that in all of these scenarios a centralization of decisions is not always possible or desirable. At the same time, unregulated access can result in over-utilization (which is suboptimal) due to each user's incentive to deviate from the common good (known as "tragedy of the commons"). Similarly, addressing the fundamental trade-offs between fairness, optimal allocation, and decentralization is essential in a cross-layer design of broadband wireless networks. This research provides a novel methodology that addresses such issues across various layers of protocol stack, and integrates these interdisciplinary studies into the academic curriculum.

无线技术的使用有可能显着降低成本并促进宽带数据访问的增长，而宽带数据访问目前主要由有线网络的安装和维护成本主导。 无线网络的一个重大挑战是跨层设计问题，本研究通过将宽带无线网络建模为一个由无线带宽（本地）和网络核心链路容量（终端）两部分组成的经济体相互作用的复杂系统来解决这个问题。 - 到结束）。 媒体访问控制 (MAC) 提供带宽复用方案，而在传输层，拥塞/速率控制决定需求，从而决定缓冲区和容量分配。 换句话说，宽带无线网络的优化设计可以被视为自治用户之间各种资源的可扩展且最佳利用/共享的问题。 经济学家一直在研究空气污染、交通管理等各种背景下的类似问题。例如，众所周知，在所有这些情况下，集中决策并不总是可能或可取的。 同时，由于每个用户都有偏离公共利益的动机（称为“公地悲剧”），不受监管的访问可能会导致过度使用（这不是最理想的）。 同样，解决公平性、最优分配和去中心化之间的基本权衡对于宽带无线网络的跨层设计至关重要。 这项研究提供了一种新颖的方法，可以解决协议栈各个层的此类问题，并将这些跨学科研究整合到学术课程中。
