Abstract:
1. A wireless gateway device configured to provide a wireless communication link between a first node and a second node, the gateway device comprising: a timer manager configured to determine a round trip time corresponding to a time at which an acknowledgement (ACK) message is expected in response to the gateway device forwarding a message from the first node to the second node, and to set a timer based on the round trip time; a link detector configured to detect when the ACK is received from the second node; a segment generator configured to generate a suppression message and to sent the suppression message to the first node if the timer expires before the corresponding ACK is received by the link detector, wherein the suppression message instructs the first node to stop sending messages until a resume message is sent to the first node; and a packet buffer configured to store the ACK when the ACK is received by the link detector.
