ABSTRACT:
A method for configuring a wireless network comprised of a control node and a multiplicity of individual nodes includes the steps of logically organizing the network into a plurality of bands Bi, wherein each of the bands Bi includes a plurality of the individual nodes and is located a number i of hops away from the control node, where i=0 through N, and N≧1, and then assigning a logical address to each of the individual nodes, and storing the assigned logical addresses in the respective individual nodes. The assigned logical address for each individual node includes a first address portion which indicates the band Bi in which that individual node is located, and a second address portion that identifies that node relative to all other individual nodes located in the same band. The network is preferably a packet-hopping wireless network in which data is communicated by transferring data packets from node-to-node over a common RF channel. Each of the individual nodes is preferably programmed to perform the step of comparing its own logical address to a routing logical address contained in each packet which it receives, and to either discard, re-transmit, or process the packet based upon the results of the comparison. The routing logical address contained in a received packet contains the full routing information required to route the packet from a sending node to a destination node along a communication path prescribed by the routing logical address. The control node is programmed to control the routing of packets by inserting the routing logical address into each packet which it transmit, detecting any unsuccessfully transmitted packets, detecting a faulty node in the communication path prescribed by the routing logical address in response to detecting an unsuccessfully transmitted packet, and changing the routing logical address of the unsuccessfully transmitted packet to a new routing logical address which prescribes a new communication path which does not include the detected faulty node. Also disclosed are a wireless network and a network node which are designed to implement the foregoing network configuration and/or routing methods.
