As networks continue to grow in size, technology-sophistication and geographical-reach, their management is becoming a major bottleneck in accommodating newer non-traditional, real-time, and mission-critical applications, even to the most experienced administrators. To address this problem, the long-term objective of the applicant's proposal is to bring the concepts of self-management to existing and emerging species of networks to create multi-technology networks with extremely large coverage, high-speeds, reliable quality-of-service (QoS), while keeping human supervision at minimal levels. Such a long-term prospect is achievable through identifying immediate problems that have both theoretical and practical significance. Following this methodology, the applicant's short-term activities will focus on the recently introduced technology of Wireless Mesh Networks (WMNs).These activities will be formulated as three main research problems. The first problem addresses the development of schemes to automate the construction of quasi-static topologies with maximum capacity. Two main approaches will be investigated to address this problem namely, graph coloring and multi-player quantum gaming theories. The second problem relates to how to dynamically allocate calculated WMN capacity efficiently and dynamically among a collection of classes of services, each endowed with a set of QoS requirements. To achieve self-managment of resource allocation, the solution will take inspiration from mechanisms in ecosystems. Finally, the third problem targets the assurance of fairness through the control of the cooperative behavior among nodes. While in other infrastructure-based networks, a centralized management entity controls the behavior of nodes to ensure fairness among users, this approach is not feasible in WMNs. Hence, a self-policing mechanism must be developed to ensure the cooperative behavior in making management decisions (e.g., resource allocation).

随着网络在规模、技术复杂性和地理覆盖范围上的不断增长，其管理正在成为适应较新的非传统、实时和任务关键型应用的主要瓶颈，即使是对最有经验的管理员也是如此。为了解决这个问题，申请人提案的长期目标是将自我管理的概念引入现有和新兴的网络种类，以创建具有极大覆盖范围、高速、可靠的服务质量(QOS)的多技术网络，同时将人工监督保持在最低水平。这样的长期前景是可以通过确定具有理论和实践意义的紧迫问题来实现的。按照这种方法，申请者的短期活动将集中在最近引入的无线网状网(WMN)技术。这些活动将被制定为三个主要研究问题。第一个问题解决了自动构建具有最大容量的准静态拓扑的方案的开发。我们将研究两种主要的方法来解决这个问题，即图着色和多人量子博弈理论。第二个问题涉及如何在服务类别的集合中高效和动态地动态地分配计算的WMN容量，每个服务类别被赋予一组服务质量要求。要实现资源配置的自我管理，解决方案将从生态系统的机制中获得灵感。最后，第三个问题通过控制节点间的合作行为来保证公平性。然而，在其他基于基础设施的网络中，由一个集中的管理实体控制节点的行为以确保用户之间的公平性，这种方法在WMN中是不可行的。因此，必须开发一种自我监管机制，以确保在做出管理决策(例如，资源分配)时的合作行为。
