摘要

移动自组网只包含移动节点,不包含接入点和中心服务器。在移动自组网环境中,由于节点出现、节点消失、节点移动等原因,导致网络中的一组节点和网络拓扑结构频繁变化,使得网络中的用户不容易获得网络中提供的服务。因此,如果没有服务发现方案,就不可能将网络中提供的服务信息告知网络中的用户。然而,由于移动自组织网络环境中没有中心服务器,因此必须检查自组织机制来收集网络中的服务信息并将其分发给用户。此外,由于网络中用户或服务的变化会随着时间的推移发生多次变化,因此应在尽可能短的时间内反映出来。为此,我们提出了一种在移动自组织网络环境下利用移动代理实现自组织实时服务分发和收集的新方案。移动代理在节点间迁移,收集网络中的服务信息并传播给网络中的用户。最后,通过仿真实验验证了该方案在服务传播时间方面的性能。

Self-Organizing Real-Time Service Dissemination and Collection Using Mobile Agents for Mobile Ad Hoc Networks
A mobile ad hoc network consists of only mobile nodes without the access points and the center server. In the mobile ad hoc network environment, a set of nodes in the network and the network topology are frequently changing due to the node appearance, the node disappearance, and the node movement so that it is not easy for users in the network to obtain the services provided in the network. Therefore, without the service discovery scheme, it is impossible to inform the users in the network of the service information provided in the network. However, since there are no center servers in the mobile ad hoc network environment, the self-organized mechanism must be examined to collect the service information in the network and disseminate them to the users. Besides, since the changes of users or the services in the network occur many times with time, they should be reflected as short time as possible. Therefore, we propose a new scheme for self-organizing real-time service dissemination and collection using mobile agents in the mobile ad hoc network environment. Mobile agents migrate among nodes to collect the service information in the network and disseminate them to the users in the network. Finally, we conducted simulation experiments to show the performance of the proposed scheme with respect to the service dissemination time.
