Abstract:
The interpretation by Transmission Control
Protocol (TCP) of loss of linkage as loss due to
congestion causes significant inefficiency in a wireless
network. Congestion that often occurs in a wireless
LAN results in further reduced performance. This
paper introduces a method of controlling congestion in
a network via a feedback mechanism called Fair
Intelligent Congestion Conirol (FICC) which is useful
for improving TCP performance in such a network,
FICC overcomes the inefficiency of TCP in
misinterpreting the link loss as congestion loss.
Simulation testing demonstrated that, by eliminating
buffer oveflows caused by congestions, FICC
provides desirable fairness, reduces delay variation
and improves effective throughput.
