中文摘要：
在社团结构网络模型下,建立社团间多副本数据转发策略的传输概率模型,提出一种基于社团结构的多副本数据传输（CMDD）策略。CMDD策略动态计算社团间移动节点的平均相遇间隔时间,并根据传输概率模型估算借助该社团分发副本可获得的成功传输概率。模拟实验表明,CMDD策略能以较低的传输延迟和较低的传输开销获得较高的数据传输成功率。
英文摘要：
The characteristics of community structure have effect on the data transmission procedure of delay tolerant mobile sensor network. Under the community network model, data delivery probabilities of multi-copied delivery were deduced. A community based multi-copy data delivery （CMDD） scheme was also proposed. By dynamically computing the average inter-meeting time between the communities and using the delivery probability formulations, the scheme can estimate the delivery probability when data are delivered through such community. Simulation results show that thepro- posed CMDD scheme achieves a relatively high data delivery ratio and a lower message delivery latency and transmis- sion overhead.
