针对移动容迟网络中的数据共享服务,提出基于社团的源路由算法(Social-based Source Routing,SSR)。将移动容迟网络中的数据共享过程分为摘要消息广播、兴趣消息回传与内容数据转发。利用分布式社团检测算法区别各节点的多社团结构,通过摘要消息广播构建节点间的社团路径(Community Path),并将共享数据沿社团路径进行基于单消息副本的转发。仿真结果表明算法在一定条件下能够达到与多副本转发算法类似的消息传输成功率,同时显著降低消息传输代价。
Aiming at the data sharing service in the mobile delay network, a community-based source routing algorithm (SSR) is proposed. The data sharing process in mobile delay network is divided into summary message broadcast, interest message return and content data forwarding. The distributed community detection algorithm is used to distinguish the multi-community structure of each node, the community path is constructed through the digest message broadcast, and the shared data is forwarded along the community path based on the single message copy. Simulation results show that under certain conditions, the algorithm can achieve the same success rate of message transmission as multi-copy forwarding algorithm while significantly reducing the cost of message transmission.
