1. In a communications network, a communication unit including a communication link with each neighboring communication unit within said network to facilitate network communications, wherein each said communication link facilitates transfer of data and is selectively controllable to further facilitate transfer of control messages, said communication unit comprising:

  • a transmitter to transmit an outgoing message to each said neighboring unit via a corresponding communication link;

    a receiver to receive an incoming message from each said neighboring unit via a corresponding communication link; and

    a processor to control said transmission and reception of said outgoing and incoming messages, wherein said processor includes;

    a communications module to examine network connectivity and determine particular communication links associated with said communication unit sufficient to enable transmission of a control message over said network to each said neighboring unit within a predetermined quantity of hops;

    a link control module to control said communication links associated with said communication unit in accordance with said determination, wherein each communication link is controlled to facilitate transmission of data and said particular communication links are controlled to further facilitate transmission of said control message to corresponding neighboring units; and

    a transmission module to facilitate transmission of said control message throughout said network by transmitting said control message via said particular communication links to corresponding neighboring units.
