Abstract—This paper mainly aims in the improvement of the
congestion control mechanism over mobile WiMAX in an
adhoc environment. Here we compare the throughputs of three
different TCP congestion control algorithms namely
Westwood+, Veno and New Reno. This paper focused on the
performance variation of three TCP congestion control
algorithms caused by both handovers and random packet
losses over mobile WiMAX. We have enhanced the protocol
with Active Queue Management (AQM) and Random Early
Detection (RED) mechanism of routing. Our ns-2 simulation
results show that Enhanced Westwood+ using the handoveraware
algorithm has the improved performance up to 10.2%
over normal TCP Westwood+.
Index Terms—Mobile W-MAX, TCP congestion control
protocols, handover.
