Abstract:
1. In a mesh network having a plurality of nodes for providing wireless access to a plurality of wireless end user devices including a first device associated with a first home node and being provided wireless access by a first roaming node different from the first home node, the plurality of nodes including a gateway node for tracking the wireless end user devices and for relaying data traffic between the mesh network and another network external to the mesh network, the gateway node being different from each of the first home node and the first roaming node, a method of routing data traffic to the first device when the first device moves from a coverage area of the first roaming node into a coverage area of a second roaming node different from each of the first home node, the first roaming node, and the gateway node, the method comprising: receiving only at the gateway node a notification from the second roaming node that the first device has moved into the coverage area of the second roaming node; receiving only at the first home node and at the first roaming node a notification from the gateway node that the first device has moved into the coverage area of the second roaming node; receiving data traffic at the first roaming node, the data traffic being destined for the first device; forwarding the data traffic from the first roaming node to the second roaming node; and forwarding the data traffic from the second roaming node to the first device.
