Now these days most of the electronic devices are connected to the internet through wired or wireless computer network. This is very popular networking terminology known as the internet of things IOT, In background each and every internet networking devices are connecting to the backbone networking server. If this backbone network route is congested then IOT devices are suffered from their services and all these things are lacking in performance. The high throughput and low latency internet services are required for each device to do well. There is a number of reasons behind the internet speed. The most important reasons are that the TCP/IP protocol does not completely use the actual channel bandwidth and congestion occurrence during the data transmission. TCP provides the connection-oriented connection. TCP may have a problem with utilizing the full bandwidth of the communication channel. Numbers of congestion control proposals have been suggested to reduce this problem. This paper presents the implementation of a quadric increase congestion control algorithm and it’s simulation through the NS3. This algorithm is based on binary increased congestion control algorithm (TCP BIC). In ns3 TCP QIC is separately implemented and tested with the different congestion control algorithms. These congestion control algorithms are TCP Westwood, BIC, NewReno, scalable and Illinois. The performance of the TCP QIC has the significance over the other congestion control algorithms in respect of throughput, goodput, delay variance and round-trip time.
