| 摘 要： | 为了缓解无线传感器网络中多对一通信方式出现的拥塞问题,提出了一种基于定向扩散路由协议的拥塞控制方法.在该方法中,转发节点根据本地的拥塞信息调整速率;sink节点周期地检测网络中的拥塞状态并将拥塞信息通过逐跳的方式反馈到源节点,而源节点根据接收到的反馈信息调节速率.仿真实验表明,该算法能有效地缓解网络中出现的拥塞,保证数...

| Abstract: | In this paper,for relieving the congestion issue of the many-to-one communication in WSN,a congestion control approach based upon the directed diffusion route protocol in wireless sensor networks is proposed.The forwarding nodes adjust their rates in terms of the local congestion information;the source nodes modulate their rates according to the feedback messages.When the sink node detects the congestion condition of the network periodically,the feedback messages are produced and transmitted hop-by-hop from... |
