Patent ID: 8892769

Claim:
A method of routing data in a multi-node wireless network operating in a process control environment and having a plurality of direct wireless connections between a plurality of network devices, wherein each of the plurality of network devices is a node of the multi-node wireless network, the method comprising: attaching graph identifiers to data packets of a first type at originating network devices to send the data packets of the first type between pairs of the plurality of network devices; routing the data packets of the first type at intermediate network devices using the graph identifiers, wherein each of the graph identifiers corresponds to one of a plurality of graphs, each of the plurality of graphs associated with two or more of the plurality of nodes and one or more of the plurality of direct wireless connections; wherein at least two of the plurality of graphs differ in at least one node associated with the respective graph; and routing data packets of a second type at intermediate network devices based on information other than graph identifiers.
