摘　　要：移动P2P网络的移动节点设备资源短缺,网络动态多变,移动节点间的协作显得越发重要.本文提出了一种灵活的移动节点间资源协作共享方案,为资源的请求者设计了基于可靠性理论的请求资源预测算法.依据排队理论为资源的提供者,构建了层次型资源调度模型.数学分析和仿真结果表明该预测算法提高了节点请求任务执行成功率,层次型资源调度模型则提高了节点协作共享资源的服务能力,降低了资源请求丢失率.Since the resources of mobile devices are scarcer and the network is dynamic,cooperation among mobile nodes is an important task.A novel flexible resource sharing and cooperating scheme among mobile nodes is proposed in the paper.A prediction algorithm of resources based on reliability theory for resources＇ requestor is also presented.According to the queue theory,a multi-level model of resource dispatching is put forward for resources＇ provider.While analysis and simulation results show that the prediction algorithm can increase success ratio of sharing resources＇ cooperation task,the resources dispatching model can significantly improve the service quality,and reduce the loss rate of resource requests.
