INTEGRATED WIRELESS DISTRIBUTION AND MESH BACKHAUL NETWORKS
First Claim
1. A method for routing traffic in a network from a specific node in said network, the method comprising the steps of:
- a) gathering information related to at least one link between said specific node and nodes adjacent to said specific node;
b) for the or each of said links, calculating a cost associated with said link between said specific node and a node adjacent to said specific node associated with said link;
c) receiving data from other nodes in said network, said data relating to costs associated with links between said other nodes and nodes adjacent to said other nodes;
d) distributing link data to said other nodes, said link data including a cost for the or each of said links between said specific node and nodes adjacent to said specific node;
e) determining routing paths from said specific node to each of said other nodes based on said data calculated in step b) and said link data received from other nodes in step c) such that a path cost associated with said routing path is minimized wherein only most recent data received from said other nodes are used in step e).

Abstract
Networks, devices and methods related to wireless networking. A wireless network using nodes that perform both distribution and backhaul functions is provided. These nodes constitute the key elements of a wireless network that would be deployed and controlled by a wireless network operator. Each node contains a distribution wireless module which is wirelessly coupled to the wireless end user device using a point to multipoint scheme. Also integrated into each node is at least one backhaul wireless module with a directional wireless antenna. Each backhaul wireless module communicates by way of a point to point wireless link with the backhaul module of one other node. The nodes in the wireless network are interconnected to form a mesh backhaul network. Because of the nature of a mesh network, data traffic can be routed around obstacles that may prevent line of site links. Furthermore, the mesh network allows dynamic routing of data traffic to avoid congestion points or downed links in the network.
