Traditional cellular wireless networks have limited capacity because of the scarcity of available spectrum and inefficient spectrum reuse. To overcome these limitations new regulatory policies are being considered to allow segments of spectrum to be dynamically shared. This project uses dynamically allocated spectrum to form multi-hop relay networks consisting of mobile nodes that forward data to base stations on behalf of each other to increase network capacity. In this work we address two challenges: (1) rapid dynamic network formation and (2) verifying and accounting for which part of the spectrum is used by which nodes. The first problem is important because it is likely that many (tens or hundreds) of nodes may attempt to join a relay network, resulting in high overhead and network formation latency. The second problem is important for motivating users to participate and compensating service providers for sharing spectrum. Algorithms for scheduling and network formation are being designed and evaluated in this work. These algorithms provide low latency and overhead, and include provisions for verifying which nodes participate in the relay network. The presence of base stations is also leveraged to quickly disseminate information to assist in relay network formation.

传统的蜂窝无线网络的容量有限，因为可用的频谱和效率低下的重复使用差异。 为了克服这些局限性，人们正在考虑新的监管政策，以使频谱段动态共享。 该项目使用动态分配的频谱形成由移动节点组成的多跳跃中继网络，该网络将数据转发到基站，代表彼此提高网络容量。 在这项工作中，我们解决了两个挑战：（1）快速动态网络形成和（2）验证和会计频谱的哪一部分使用。 第一个问题很重要，因为许多节点可能会尝试加入继电器网络，从而导致高架开销和网络形成延迟。 第二个问题对于激励用户参与和补偿服务提供商共享频谱很重要。 在这项工作中，正在设计和评估用于调度和网络形成的算法。 这些算法提供低潜伏期和开销，并包括验证节点参与继电器网络的规定。 也利用基站的存在来快速传播信息以协助继电器网络形成。
