延迟容忍移动传感器网络(DTMSN)是一种广泛应用的数据采集网络.提出一种基于社会网络的数据传输策略SNBD(social network-based data delivery scheme)应用于DTMSN.SNBD引入社会网络中的相互作用强度和相称机制,通过计算两传感器节点之间的相互作用强度值和相称值,作为消息传输时选择下一跳的依据.为了优化节点队列,SNBD采用消息的重要因子和TTL决定队列中消息传递的优先顺序和丢弃原则.模拟实验表明,与现有的几种数据传输策略相比,SNBD不但具有较高的数据传输成功率,而且具有较低的数据传输能耗和传输延迟,并且通过分析发现SNBD的网络寿命是SRAD和FAD的8倍.
Delay-tolerant mobile sensor network (DTMSN) is a widely used data acquisition network, and proposes a social network-based data transmission scheme (SNBD) applied to DTMSN.SNBD introduces social network interaction Intensity and proportionality mechanism, the value of the interaction between the two sensor nodes is calculated as the basis for selecting the next hop for message transmission.In order to optimize the node queue, SNBD uses the important factors of the message and the TTL to decide the message passing in the queue And the principle of discarding.The simulation results show that compared with several existing data transmission strategies, SNBD not only has a higher success rate of data transmission, but also has lower data transmission energy consumption and transmission delay, and through analysis SNBD network life is found to be 8 times the SRAD and FAD.
