为解决现有移动对等覆盖网络抗扰动性差和资源查询成功率低的问题,提出一种基于k-派系社区结构的移动对等覆盖网,按照节点加入的先后顺序形成多个k-派系,并通过对拓扑结构动态变化的自适应和资源列表共享实现系统的抗扰动性。利用改进的Gossip算法进行拓扑控制信息和资源共享列表的数据分发,保证系统在扰动情况下的动态调整效率,有效降低网络负载。提出一个三维移动对等覆盖网在扰动情况下的性能评价模型,并对多种覆盖网在该模型下的性能进行了评估。评估结果表明,所提覆盖网在剧烈扰动情况下保持了较高的查询成功率。
In order to solve the problem of poor anti-interference ability of existing mobile peer-to-peer overlay networks and low success rate of resource query, this paper proposes a mobile peer-to-peer overlay network based on k-faction community structure, which forms multiple k-factions according to the order of nodes joining, The anti-disturbance of the system is realized by adaptively changing the topological structure and resource list. The improved Gossip algorithm is applied to the data distribution of topological control information and resource sharing list to ensure the dynamic adjustment efficiency of the system in case of disturbance and reduce the network load effectively. A performance evaluation model of three-dimensional mobile peer-to-peer overlay network under disturbances is proposed, and the performance of multiple overlay networks under this model is evaluated. The assessment results show that the proposed overlay network maintains a high query success rate under severe disturbance.
