摘　　要：提出了适用于延迟容忍移动传感器网络的交叠社团数据转发机制。首先,提出了节点初始社团结构检测方法。其次,综合考虑节点连接紧密度、连接稳定度二维因素,设计了交叠社团节点感知方法。进而,充分利用重叠社区节点提出了高效的数据转发机制,以提高社团内与社团间数据转发的效率。仿真结果表明,相比已有方法,所提方法可分别提高有效检测率、数据投递率、投递时延性能15%、9%、16%以上。An effective data forwarding mechanism is proposed for overlapping community in delay tolerant mobile sensor networks.Firstly,an initial community structure detection method of nodes is designed.Then,a node perception method for overlapping community is proposed,taking both the tightness of node connection and the stability of connection into account.An efficient data forwarding mechanism is presented to enhance the efficiency of data forwarding within and outside the community,by taking full advantages of overlapping community nodes.Simulation results show that the proposed mechanism can respectively improve the performances of effective detection rate,data delivery rate and delivery delay about more than 15%,9%,and 16%respectively,than existing mechanisms.
