1. A method for a node currently synchronized to a first network, having a first Network ID to synchronize to a second network having a second Network ID, the method comprising the steps of:

  • receiving a beacon containing the second Network ID;

    determining that the second Network ID differs from the first Network ID;

    determining that a condition exists that requires merging the first network with the second network;

    synchronizing to the second network when the condition exists, otherwise maintaining synchronization to the first network; and

    determining if the first network is synchronized to a fixed network coordinator; and

    wherein the step of synchronizing to the second network when the condition exists comprises the step of synchronizing to the second network only when it is determined that the first network is not synchronized to the fixed network coordinator and when the condition exists.
