    public class RxCoordination
extends MACActorBase
    RxCoordination class is responsible for the sequence of events in response to a session setup request. When a RTS packet is received, RxCoordination sends a CTS back after SIFS seconds if NAV is zero (i.e. channel is available); when a data packet is received, a Ack is sent back after SIFS seconds and the data packet received will be forwarded to the network layer. RxCoordination also notifies TxCoordination process of the receipt of either CTS or Ack.
