1. In a packet communication network with a plurality of stationary nodes, a method by which a roaming node may establish a communication link with said network comprising the steps of:

  • transmitting a link acquisition packet to one or more of said stationary nodes;

    receiving a response packet from each of said stationary nodes that successfully receives said link acquisition packet;

    determining from data in said received response packets the one of said stationary nodes that provides the best communication link;

    selecting the one of said stationary nodes that provides the best communication link by transmitting to said selected stationary node a packet informing said selected stationary node that said selected stationary node is a current parent node for said roaming node; and

    transmitting data packets to nodes in the network using an identifier of said parent node as part of the return identifier for said roaming node.
