Abstract
A method of transmitting routing information within a network is disclosed. Accordingly, in response to a change in preferred route from one node to another node within the network, the method includes 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. The 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.

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 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.
A node of a communications network, comprising a memory which stores a routing table, wherein the routing table comprises a set of entries, with one entry for each node of the network other than the node itself, wherein each entry comprises a digital word in which at least each node in the mesh network other than the one node and the node to which the entry relates is represented by a single binary bit, where the binary bit associated with each node is set to one value if that node is in the preferred route from the node itself to the node to which the entry relates, and the other value if that node is not in the preferred route.
A node routing table update message comprising a digital word in which at least each node in the network other than the source node from which the message originates and a destination node is represented by a single binary bit, where the 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.
