Implement a network of wireless sensors on factory by standard control systems
A wireless node would normally be sent to its “parent.” If a node fails due to hardware failure or other reason, its neighbors are able to modify the route to transfer data to the next station.
Mesh networks use different communication protocols. A protocol is the vector ad hoc on demand (AODV) routing. When using AODV protocol network is quiet until a connection is required. When a node requires a connection broadcasts a request to connect to the network. Other nodes on the network broadcasts the request for registration in the same time, the ID of the requesting node. Assuming that the communication channels were initially put in place throughout the network, the receiving node sends a reply to the sender. Communication between stations is generally determined by the least number of “hops” through other nodes. When a communication link is not a routing error is returned to the original sending node and the process repeats. (more…)
