Abstract
A wireless network includes a leaf node, which generates a data message. The data message is routed through infrastructure nodes to a gateway infrastructure node, which is coupled to a wired network. A wireless interface module is also coupled to the wired network and communicates with the gateway infrastructure node. Multiple copies of the data message are created in the wireless network due to redundancy mechanisms supported in the wireless network, such as redundant connectivity and redundant message routing. The multiple copies of the data message are received at the gateway infrastructure node or the wireless interface module, which identifies the copies and communicates a single copy of the data message over the wired network to a destination. In this way, the redundancy mechanisms supported in the wireless network are concealed from wired components coupled to the wired network.
