This paper proposes a new method of TCP congestion control for the IEEE 802.15.4 standard.This method, which evolved from TCP Newreno, is to be adopted on an IEEE 802.15.4 based network.The implementation of TCP Newreno on Wireless Sensor Network (WSN) is unable to classify losses of segments caused by congestion, wireless channel error or segment mishandling.An increase in TCP Newreno aggressive behavior on congestion avoidance phase has also led to frequent occurrence of congestion due to the low rate or limited bandwidth of IEEE 802.15.4.The proposed method is named LR-Newreno.LR indicates Low Rate -WPAN network specifications for WSN based on IEEE 802.15.4 standard.We propose enhancement on window growth function (addictive increase) and window decrease function (multiplicative decrease) in compliance with WSN characteristics.The new method has been simulated on network simulator-2 environment.The result shows that the TCP LR-Newreno provides better performance in term of several parameters such as throughput, data drop rate and energy consumption when compared to original TCP Newreno.
