Performance Evaluation of TCP-P in Wireless Environment (original) (raw)

Improving the performance of an active research area. Main reason behind performance degradation of TCP is not having ability to detect actual reason of packet losses in wireless environment. In this paper, we are providing a simulation results f (TCP-Performance). TCP-P is intelligent protocol in wireless environment which is able to distinguish actual reasons for packet losses and applies an appropriate solution to packet loss. TCP-P deals with main three issues, Congestion in network, D losses. TCP-P consists of Congestion avoidance algorithm and Disconnection detection algorithm with some changes in TCP header part. If congestion is occurring in network then congestion avoidance algorithm is appl In congestion avoidance algorithm, TCP and accordingly set a sending bu er value, so that it can prevent system from happening congestion. In disconnection detection algorithm, TCP network. TCP-P modifies header of TCP packet so that loss packet can itself notify sender that it is lost. This paper describes the design of TCP simulator. Results from simulations show that TCP TCP-Vegas, 7% more e cient than TCP Reno. But we can say TCP-P is more e issues of TCP in wireless environment. Improving the performance of the transmission control protocol (TCP) in wireless environment has been an active research area. Main reason behind performance degradation of TCP is not having ability to detect actual reason of packet losses in wireless environment. In this paper, we are providing a simulation results f P is intelligent protocol in wireless environment which is able to distinguish actual reasons for packet losses and applies an appropriate solution to packet loss. P deals with main three issues, Congestion in network, Disconnection in network and random packet P consists of Congestion avoidance algorithm and Disconnection detection algorithm with some changes in TCP header part. If congestion is occurring in network then congestion avoidance algorithm is appl In congestion avoidance algorithm, TCP-P calculates number of sending packets and receiving acknowledgments er value, so that it can prevent system from happening congestion. In disconnection detection algorithm, TCP-P senses medium continuously to detect a happening disconnection in P modifies header of TCP packet so that loss packet can itself notify sender that it is lost. This paper describes the design of TCP-P, and presents results from experiments using the NS simulator. Results from simulations show that TCP-P is 4% more efficient than TCP-Tahoe, 5% more e cient than TCP-Sack and equally e cient in performance as of TCP-Reno and TCP P is more e cient than TCP-Reno and TCP-New Reno since it is able to solve more (TCP) in wireless environment has been an active research area.
