Performance Evaluation of Snoop Protocol for Wireless Networks
Sherif Moussa, Mohammad Wahba, Salah Ramadan · Journal of Advances in Computer Networks · 2015
The performance of TCP decreases when high bit error rate exists over wireless link.TCP responds by mistake to all packet losses by invoking congestion control algorithm, resulting in degraded end-to-end performance.Several solutions have been proposed to improve the performance of transmission control protocol (TCP) over wireless link.In this paper, the implementation of snoop protocol, as a TCP-aware link level over wireless networks, and conventional TCP are compared using wired infrastructure.All simulations were performed using network simulator 2 (NS-2).The simulation results focus on key performance metrics such as throughput, congestion control, end-to-end time delay, and packet loss rate.
