The Wireless Sensor Networks(WSNs) is promising technology toward the Internet of Things(IoTs). Therefore, the routing protocols of WSN should be able to achieve real-time, reliability, which are typical requirements for IoT applications. In the literature, many multipath routing protocols are exploited to achieve the requirements, however, they have the constraints of energy consumption and scale owing to the participation of many nodes to maintain a large number of paths. These constraints would degrade the performance of IoTs services used in various environments. To address this issue, we propose the routing scheme to enable cooperation among the paths with a bridge node. As the bridge node observes the packet transmission on the path, it could prevent and recover the detected problems such as transmission failure and delay. That is, the multipath is reinforced through the cooperation by inter path communication based on the bridge node. As a result, the proposed scheme could achieve real-time, reliability at WSN which is exploited for IoT applications, while also resolving restrictions on energy consumption by using less number of paths.

无线传感器网络（WSN）是面向物联网（IoT）的有前途的技术。因此，WSN的路由协议应该能够实现实时，可靠，这是物联网应用的典型要求。在文献中，许多多路径路由协议被用来达到要求，但是由于许多节点的参与以维持大量路径，它们具有能耗和规模的约束。这些限制将降低各种环境中使用的物联网服务的性能。为了解决这个问题，我们提出了一种路由方案，以实现与桥节点之间的路径之间的协作。当网桥节点观察路径上的数据包传输时，它可以防止和恢复检测到的问题，例如传输失败和延迟。那是，通过基于网桥节点的路径间通信的协作来增强多路径。结果，提出的方案可以在用于物联网应用的WSN处实现实时，可靠，同时还可以通过使用较少的路径来解决对能耗的限制。
