Abstract:
1. A method for distributing proxying error information in a wireless network comprising a plurality of nodes, the method comprising: associating a proxy node with a non-routable node, wherein the proxy node includes a proxy table; sending a data packet from an originator node to the proxy node for delivery to the non-routable node; disassociating the non-routable node from the proxy node; updating the proxy table by the proxy node to remove the non-routable node from the proxy table; determining by the proxy node that the non-routable device has disassociated from the proxy node by the proxy node determining that the non-routable node is not included within the proxy table; sending a proxy error message from the proxy node to the originator node to inform the originator node that the non-routable node is no longer proxied by the proxy node; and starting a route discovery process for the non-routable node by the originator node.
