Method and system for improving wireless link efficiency

摘要

One embodiment of the present invention provides a system for improving transmission efficiency of a wireless link. During operation, the system receives a packet for transmission, where in the packet includes an original sequence number. The system then modifies the packet by including a virtual sequence number in a header of the packet and including the original sequence number in a payload of the modified packet. The system further aggregates a number of modified packets into an aggregate frame and transmits the aggregate frame to a destination device. The virtual sequence number facilitates stateless transmission of the encapsulated packets and allows the aggregate frame to have a maximum allowable number of packets while accommodating both re-transmitted packets and regular packets.

主权项

1. A method of wireless link transmission, comprising:
selecting a virtual sequence number for each of a first set of packets to be transmitted in an aggregate frame, wherein the first set of packets includes one or more regular packets, and includes one or more retransmission packets to be retransmitted with the one or more regular packets in the aggregate frame; modifying a respective packet of the first set of packets by:
modifying a payload of the respective packet to include an original sequence number of the respective packet; andmodifying a header of the respective packet to include a virtual sequence number selected for the respective packet; generating an aggregate frame which includes the first set of packets modified to include a corresponding virtual sequence number; and transmitting the aggregate frame to a destination device over a wireless link.
