Effect of Node Speed and Packet Size on the Performance of the Modifications Transmission Control Protocol

Transport Control Protocol (TCP) provides user with reliable data communication in cloud networks. Several control mechanisms of TCP have been introduced in order engage reliable smart cities communication Nonetheless, the conventional additive increase and aggressive multiplied decrease strategies that TCP protocol presently uses in congestion window adjustment could not fit well with the high-speed network bandwidth. Hence, high-speed transport protocols appropriate for next-generation Internet is now a subject of interest among scholars. Accordingly, the performance of three techniques of TCP protocols namely SACK TCP, TAHOE TCP and RENO TCP impacted by the node speed and packet size examined and reviewed in this study. The TCP protocols were assessed using average throughput (TP) and Average End-to-End (E2E) delay performance metrics. Meanwhile, the routing protocols were tested using the NS2 simulator. The proposed method is hence practicable in theory. As verification to the method, NS-2 simulations are presented
