Benefits of technology

This approach enhances transmission efficiency by allowing the maximum number of packets to be transmitted in an aggregate frame, improving link efficiency even under high packet error rates and reducing overhead, compared to conventional IEEE 802.11 wireless links.

Problems solved by technology

Wireless networks such as IEEE 802.11a / b / g / n / ac networks, however, require explicit acknowledgement from the receiver for every packet due to the unreliable nature of the communication medium.
These requirements often lead to low transmission efficiency in IEEE 802.11 wireless links.

Embodiment Construction

[0030]The following description is presented to enable any person skilled in the art to make and use the embodiments, and is provided in the context of a particular application and its requirements. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present disclosure. Thus, the present invention is not limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0031]Some embodiments of the present invention enhance the transmission efficiency in IEEE 802.11 wireless links by using virtual sequence numbers for packets transmitted in an aggregate frame, which allows packets to be retransmitted with other regular packets in an aggregate frame that can accommodate the maximum number of packets. In particular, the vi...

Abstract

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.

Description

RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Patent Application No. 61 / 729,219, filed 21 Nov. 2012, entitled “METHOD AND SYSTEM FOR IMPROVING WIRELESS LINK EFFICIENCY.”BACKGROUND[0002]1. Field[0003]This disclosure is generally related to wireless networks. More specifically, this disclosure is related to a method and system for improving transmission efficiency in a wireless link.[0004]2. Related Art[0005]In recent years, the phenomenal growth of mobile devices, such as smart phones and tablet computers, has resulted in a huge demand in wireless networks. Particularly, Wi-Fi networks, which are based on the IEEE-802.11 family of standards, are becoming increasingly ubiquitous.[0006]In conventional wired layer-2 networks such as 10base-T, 100base-T, or 1000base-T Ethernet, transmission of a packet is typically not followed by an acknowledgement from the receiver. Reliable data delivery depends on upper layer protocols, such as Transmission Control Pr...
