中文摘要：
利用节点保存的相遇历史信息，提出一种节点连接态势感知的消息传输策略，通过建立时序图模型估计节点间的连接态势，以时延、投递率以及负载率为联合优化目标参数，采用均衡和量化方法，为消息分布式地选择最佳中继节点。仿真结果表明，所提出的消息传输策略能够有效降低网络负载48％以上，并改善消息投递率和平均时延性能。
英文摘要：
A novel connection status aware cost efficient message transmission mechanism （CSAMT） was proposed. The presented mechanism constructed a dynamic temporal graph matrix based on historical data stored in the cache of the peers to estimate the connection status. Furthermore, the delay, delivery ratio and Overhead together were selected as ob ject optimizing parameters, and then the preferable relay peers could be distributively chosen by adopting equalization and quantification schemes proposed. Numerical results show that CSAMT mechanism can efficiently reduce overhead for more than 48% while the messaze delivery ratio and latency are improved also.
