Abstract:
1. A method of transmitting routing information within a network, the method comprising: in response to a change in preferred route from one node to another node within the network, providing a message comprising a digital word in which at least each node in the mesh network other than the one node and the another node is represented by a single binary bit, where the single binary bit associated with each node is set to one value if the node is in the preferred route, and the other value if the node is not in the preferred route; wherein the preferred route is the route with the lowest hop count, the lowest hop count determined by the number of bits in the digital word set to the value indicating that a node is in the preferred route; and wherein the method further comprises receiving a first message from a node which neighbors said one node informing said one node of a shorter route if the route provided by said one node is longer than the preferred route in a routing table of the node which neighbors said one node.
