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.
