ABSTRACT:
A method routes packets in a wireless network which includes a control node and a multiplicity of individual nodes. The method includes: inserting a routing logical address into each packet which is transmitted between a sending node and a destination node, wherein the routing logical address contains the full routing information required to route the packet from the sending node to the destination node along a communication path prescribed by the routing logical address; 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.
