| 摘 要： | 首先讨论了主动节点为支持个性化服务和公平服务需要解决的资源管理问题。针对个性化服务支持,提出了一个简洁而通用的NodeOS服务模型;针对公平服务支持,系统全面地讨论了节点的资源管理问题,包括资源分配与调整、资源准入控制、资源使用监视及管制等,并一一给出了解决方案。接着讨论了主动节点的安全问题及基于授权的节点安全保护机制,并详细叙述了将KeyNote信任管理系统嵌入到NodeOS中的实施细节。

| Abstract: | The resource management problems that an active node must solve in order to provide customized and fair services are discussed. To support customized services, a simple and general model for NodeOS services is proposed. To support fairness, the resource management problems including resource allocation and adaptation, entry controlling, usage monitoring and policing are systematically studied, and the scheme to resolve them is given. The security problems which active nodes are confronted are discussed, and the active node protecting mechanism with authorization-based techniques is analyzed. How to embed KeyNote trust management system into NodeOS is illustrated with details. |
