摘要： 针对无线传感器网络导航中出现的拥塞问题，提出一种拥塞检测和缓解算法。每个节点周期检测其导航的用户数量，根据用户数量是否超过上限判断其所在路径是否发生拥塞，若发生拥塞，采用拥塞缓解算法，导航相应用户到其他路径，从而使用户更加快速、安全地逃离危险区域。仿真实验结果表明，该方法在导航时能有效控制网络拥塞，使路径负载更加平衡。

Abstract: In this paper, an algorithm is proposed to detect and mitigate congestion, which occurrs in navigating with Wireless Sensor Network (WSN) in emergency. Each node detects the number of users to judge whether congestion is occurred. If congestion occurs, navigate the user to the other path, users can escape from the dangerous area more quickly and safely. Simulation results show this method can control network congestion efficiently, and make the load of roads more balanced.
