GOAL
To Optimise Wireless Local Area Network (WLAN) in terms of its
Reliability (data packet loss) and Speed. This is a Honours Project by
the University of Adelaide. Our WLAN complies with IEEE 802.11b. This
means, we are operating on 2.4 GHz Free Spectrum Band and the optimal
speed is up to 11 Mega-bit per second (Mbps).

DISCUSSION
We are using the Minitar Access Points with Realtek RTL8181 CPU
processor.
This project focus on improving the data transmission by writing
kernel programs in the access points to dynamically change to the best
Signal to Noise Ratio channel when the current one experiences bad
performance {namely Dynamic Channel Switching (DCS) method - between
channel 1 to 11), and finding the optimal packet structure between any
APs under any condition (between 30 to 2346 bytes standard).
We have questions and would like any open suggestion of ideas to help
us better the performance of wireless LAN. Currently we have
questions:
QUESTION 1
Any suggestions on how to tackle the problem listed above?
QUESTION 2
In order to write the optimisation algorithm, we need a few values
from the AP registers - namely data packet loss value from the access
point client, and the time taken for transmission. From the Realtek
data sheet I noticed a few values that resembled the values we need,
but not sure which one should take as the measurement for data packet
loss:
1. Receive Error Count (ETH_RXER) from either the Ethernet 0 or 1
Register set that increments by 1 for each valid packet received. Or
2. Received Error (RER) or Receive OK (ROK) that indicated packet
receptions at the receiving end from the Interrupt Status Register
(WLAN_ISR) ?
QUESTION 3
Given that Realtek has not released the full version driver for the
Minitar Access Point, should we -
1. Write our C program driver algorithms into the AP kernel source
code? Or
2. Write Shell Script to accommodate our algorithms?
CONCLUSION
This WLANOptimisationWorkingGroup [9] has not come to final
conclusion yet. A formal announcement will be made before conclusion
of this group.
