My Research Interests: Adaptive MAC design in Wireless LAN:

Link adaptation on 802.11 is a hot-topic for recent years. My research is based on an experiment approach to evaluate the feasibility and effects of applying link adaptation schemes to a 802.11 WLAN.

Basically, link adaptation scheme on a WLAN is classified in two kinds:
  1. Traditional Link Adaptation scheme[6,7,8,9,10,11]. Based on the varying characteristics of a single wireless link. Tx-Rx pairs adopt adaptive frame size, and transmission rate.
  2. Packet scheduling scheme. In addition to claim themselves as "channel-state-dependent", These schemes [1,2] utilized the feature that WLAN is a shared media network. Thus, multi-user diversity could be exploited to enhance overall network goodput. In a variation of this kind of study, the frame scheduling[3][4][5] is used to avoid collision and maximize throughput and fairness but without using the channel-state information. This kind of research is popular in computer science society where people are not very familiar with the varying characteristics of wireless channel.


The other  work is to design 802.11 Compatible MAC scheme for multi-hop ad-hoc network.
