摘要:无线传感器网络广泛应用于人类社会生活的各个方面，例如灾难预警、工业控制等.而此类应用有很多不仅对数据的实时性存在较高要求，同时对鲁棒性也存在要求.此类问题主要挑战是要兼顾延迟性能和鲁棒性.针对这个挑战，提出了低延迟高鲁棒性的路由协议（RDR），RDR通过独特的路径探测寻找延迟较短、鲁棒性较强的路径，以此降低传输延迟，利用周围节点协助转发解决不稳定链路，增强鲁棒性，使得网络中的节点可以在良好的网络环境或恶劣的网络环境中都保持较好的延迟表现，同时保证网络中节点可以进行端到端通信，不再局限于单向数据收集.使用OMNeT++平台围绕延迟、鲁棒性等多个角度进行了大量的仿真实验，通过理论分析和仿真实验结合，从各个方面说明了所提协议可以保证较低的端到端延迟，并且具有很强的鲁棒性.



Abstract:Wireless sensor networks are widely used in all aspects of human social life, such as disaster warning and industrial control. Many such applications need to meet not only high real-time data requirements, but also robustness of the requirements. The main challenge for this type of problem is to balance performance and robustness. In order to solve this problem, this article proposes a low latency and high robust routing protocol (RDR). RDR finds a shorter delay and strong resistance path through unique path detection to reduce the propagation delay. It also uses the surrounding nodes to assist in forwarding to solve the unstable link and enhance the robustness. As a result, the nodes in the network can maintain good delay performance in both good network environment and bad network environment, and also communicate with each other instead of limiting to one-way data collection. The paper uses OMNeT++ platform to carry out a large number of simulation experiments around delays and robustness. Theoretical analysis and simulation experiments show that RDR can guarantee lower end-to-end delay and strong robustness.
