Paper Title:

Cooperative Scheduling Via Pipelining in 802.11 Wireless Networks

Download ​pdf

Motivation

• Per packet Micro-scheduling need firmware/hardware(MAC) upgrade
• Macro-scheduling could be done in multiple packet basis peridodically, e.g 10ms. *such cooperative scheduling extensions can be supported using a new layer on top of the existing MAC layer.

Features of Scheme

• each node conducts "global scheduling" based on "load infomation" of all other nodes.

Weakness

• not a solution for multi-hop
• no solution for signalling loss, wrong scheduling automatically fades out in next cycle.
