Abstract
Wireless networks are growing rapidly. TCP is the most widely-used protocol on Internet and so optimizing TCP performance is very important for fast efficient data transfer. The different existing TCP variants and solutions they have not been analyzed together to identify the bottlenecks in wireless networks. TCP has a major problem in its congestion control algorithm which does not allow the flow to achieve the full available bandwidth on fast long-distance links. This problem has been studied in this study using a new high speed congestion control TCP protocol based on the Newton Raphson algorithm This study further analyses involving six TCP performance evaluation constraints namely, TCP full bandwidth utilization, throughput, packet loss rate, fairness in sharing bandwidth, friendliness in short-RTT and long-RTT and these constraints are used to evaluate the proposed Newton Raphson Congestion Control (NRC-TCP) performance. This study shows that the proposed algorithm performs better compared with the other methods of application.
Highlights
WestwoodNew estimated congestion window algorithm based on the network status and Retranmission
Several solutions exist to attain loss-tolerant multimedia applications and good evolving from very high speed and long distance TCP perfromance
A lot of experiments have been performed with any congestion in the following network to study and test the performance of High speed TCP variants with the proposed NRC congestion control mechanism and the results are compared with the previous high speed TCP variants such as BIC-TCP, CUBIC, High Speed TCP, H-TCP, Scalable TCP, using NS-2 with TCPLinux modification
Summary
WestwoodNew estimated congestion window algorithm based on the network status and Retranmission. Several high speed data applications require the stability of the Internet which is TimeOuts to achives better throughput than TCP Westwood and decreases the delay (Hagag and EISayed, 2012; Sheth et al, 2013). These High speed TCP Networks Standard TCP, the new congestion control algorithms are are characterized by (BDP) Bandwidth and Delay being developed because of more and more computers get Product which represents the total number of packets to interconnected only using TCP. This study evaluates the performance of proposed NRC-TCP using simulation of proposed model in NS-2 with TCP-Linux modification (Singh et al, 2012). The results of this simulation are compared with the high speed TCP variants.
