中文摘要：

针对物联网中无线传感器节点传输数据的需求,在分析现有无线传感器网络数据传输协议的基础上,提出了基于机会主义的并发传输的数据传输协议。该方法是通过适度的容忍并发传输冲突和节点机会多跳相结合实现的。最后,对所提出的协议进行了仿真验证。结果表明,所提出的协议能够有效地避免节点之间的竞争,提高了数据传输效率,降低了能耗。

英文摘要：

In view of the requirements for wireless sensor nodes to transmit data in the Internet of things,on the basis of the analysis of existing wireless sensor network data transmission protocol,aprotocol model of opportunistic concurrent transmission is proposed in this paper.The method is realized by moderate tolerating of conflicts of concurrent transmission and nodes multi-hop opportunistic.Finally,the proposed protocol is simulated and verified.The results show that the proposed protocol algorithm can effectively avoid the competition between nodes,improve the data collection efficiency of wireless sensor networks and reduce the overall energy consumption.
