  • determining a delay cost for each of a plurality of access points in the wireless network, each of said access points having zero or more wireless nodes associated with it;

    when the delay costs are not equal and when a difference in delay costs of two access points exceeds a cost to move a wireless node then;

    determining an access point with the greatest delay cost;

    for each wireless node associated with the access point with the greatest delay cost, determining an overall cost associated with moving the wireless node from the access point to each of one or more other access points of the plurality of access points; and

    moving the wireless node to the access point of the one or more other access points having a lowest overall cost associated with moving the wireless node.
