摘　　要：如何将节点收集到的数据有效的传递到汇聚点是移动传感器网络(mobile sensor network,MSN)中数据传输需要解决的主要问题,在面向社会环境的MSN中,可利用节点载体的行为特性来辅助设计数据传输方法,为此提出基于社会行为的数据传输策略(social behavior based data delivery scheme,SBD),其综合利用了人具有偏好地点以及社会活跃性不同等社会特性来辅助数据传输,并利用消息被汇聚点接收的可能性来决定队列中消息的发送顺序和丢弃原则。基于节点真实移动轨迹的实验表明,SBD较好的实现了数据传输成功率和传输能耗以及传输延迟之间的平衡。The main problem needs to solved in the mobile sensor network is how to delivering data effectively to the sink nodes. In the social oriented network environment, human behavior properties could be used in the design of the data forwarding algorithms. Accordingly, we propose a social behavior based data delivery scheme （SBD）, which takes advantage of the stable human properties that they have preference locations and their activities are different, it also employs the possibility of message being received by sinks to decide message＇s transmission and dropping. Experiments based on mobility traces from the real world show that SBD strategy achieves well tradeoff between the data delivery rario/delay and the overhead.
