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增强宽带数据访问的增长，这目前由有线网络的安装和维护成本主导。 无线网络中的一个重大挑战是跨层设计的问题，该研究通过将宽带无线网络建模为具有两个部分的复杂交互经济体系统，即无线带宽（本地）和网络核心链接链接（端到端）。 媒体访问控制（MAC）提供了带宽多路复用方案，而在运输层，拥塞/费率控制决定了需求，因此缓冲和容量分配。 换句话说，宽带无线网络的最佳设计可以视为自主用户中各种资源的可扩展利用率/共享的问题。 经济学家一直在研究各种情况下的类似问题，例如空气污染，交通管理等。 同时，由于每个用户的动力偏离共同利益（称为“公共悲剧”），因此不受监管的访问可能导致过度利用（这是次优的）。 同样，解决公平，最佳分配和权力下放之间的基本权衡是在宽带无线网络的跨层设计中必不可少的。 这项研究提供了一种新的方法，可以解决各个协议堆栈中的此类问题，并将这些跨学科研究整合到学术课程中。
