Performance improvement of TCP new reno using one way delay measurement

Abstract

Well known TCP NewReno protocol when used with wire-cum-wireless network its performance decreases, due to the inability to discriminate wireless loss with congestion loss. One way delay can give better network characteristics than approximate RTT used in TCP congestion control algorithms. In this paper, we have proposed a modified version of TCP NewReno based on one-way delay measurement. We called it as WNewReno. Our proposed algorithm detects wireless loss and improves performance. Simulations are carried out using ns-2.34.
