摘要： A wireless network includes a leaf node (110a-110f), which generates a data message. The data message is routed through infrastructure nodes (108a-108e) to a gateway infrastructure node (112), which is coupled to a wired network (106). A wireless interface module (114) 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.

摘要： A method includes receiving data at a first wireless node in a wireless network, where the data is associated with an industrial control and automation system. The method also includes decrypting the received data using a first encryption key to produce decrypted data and encrypting the decrypted data using a second encryption key to produce encrypted data. The method further includes communicating the encrypted data to at least a second wireless node in the wireless network. Another method includes generating first data at a first wireless node in a wireless network, where the data is associated with an industrial control and automation system. The other method also includes encrypting the first data using an encryption key and transmitting the first data to multiple second wireless nodes in the wireless network, where the second wireless nodes are capable of using the same encryption key to decrypt the first data.

摘要： A wireless network includes leaf nodes (such as wireless sensors or other wireless devices) and infrastructure nodes (such as access points). The leaf nodes communicate data messages to the infrastructure nodes. The infrastructure nodes communicate the data messages to gateway infrastructure nodes, which transmit the data messages over a wired network. The leaf nodes may communicate data messages to multiple infrastructure nodes in various ways. For example, the leaf nodes may transmit multiple messages, one at a time, to multiple infrastructure nodes. The leaf nodes may also broadcast a single message to multiple infrastructure nodes. In addition, the leaf nodes may communicate a single message containing a group identifier (such as a multi-cast group address) associated with multiple infrastructure nodes. In this way, communications from the leaf nodes may be more reliable. This may be particularly useful, for example, in networks such as 802.11-based networks.
