无线传感器网络(WSNs)在农业领域得到了广泛应用，多域软件定义网络(SDN)的出现提高了无线资源利用率，加强了网络管理。近年来，多域SDN被应用于农业传感器网络，即多域软件定义的无线传感器网络(SDWSN)。然而，当控制农业网络的SDN突然变得不可用时，无论是域内还是域间，传感器网络通信都会因为失去控制而异常。此外，即使控制器再次可用，也存在控制器和交换机信息更新问题。针对这些问题，本文提出了一种基于Open vSwitch扩展的多域SDWSN解决方案，提高了农业网络的生存性和稳定性。我们通过设计连接状态机制、L2和L3上的通信机制以及基于Open vSwitch的信息更新机制来实现这一点。实验结果表明，在控制器失效期间，无论是农业域间还是域内，传感器交换机都能尽快进入故障恢复模式，使传感器网络保持稳定的吞吐量，故障恢复时间在300ms以下，丢包率低。此外，一旦控制器变得可用，域可以再次平稳地控制域网络。这种基于Open vSwitch扩展的方法可以增强精准农业中多域SDWSN的生存性和稳定性。
Wireless sensor networks (WSNs) have been widely applied in agriculture field; meanwhile, the advent of multi-domain software-defined networks (SDNs) have improved the wireless resource utilization rate and strengthened network management. In recent times, multi-domain SDNs have been applied to agricultural sensor networks, namely multi-domain software-defined wireless sensor networks (SDWSNs). However, when the SDNs controlling agriculture networks suddenly become unavailable, whether intra-domain or inter-domain, sensor network communication is abnormal because of the loss of control. Moreover, there are controller and switch info-updating problems even if the controller becomes available again. To resolve these problems, this paper proposes a new approach based on an Open vSwitch extension for multi-domain SDWSNs, which can enhance agriculture network survivability and stability. We achieved this by designing a connection-state mechanism, a communication mechanism on both L2 and L3, and an info-updating mechanism based on Open vSwitch. The experimental results show that, whether it is agricultural inter-domain or intra-domain during the controller failure period, the sensor switches can enter failure recovery mode as soon as possible so that the sensor network keeps a stable throughput, a short failure recovery time below 300 ms, and low packet loss. Further, the domain can smoothly control the domain network again once the controller becomes available. This approach based on an Open vSwitch extension can enhance the survivability and stability of multi-domain SDWSNs in precision agriculture.
