TCP performance optimization using Congestion Window Limit in Ad Hoc Networks with MAC Frame Aggregation

Min-Woo Kang,Heemin Park,Joon-Sang Park

Abstract

MAC frame aggregation is a method that combines multiple MPDUs (MAC protocol data units) into one PPDU (PHY protocol data units) to enhance network performance at the MAC layer. In ad hoc networks, TCP underperforms due to the congestion window overshooting problem and thus by setting CWL (congestion window limit) TCP performance can be improved. In this paper, we investigate the problem of setting CWL for TCP performance optimization in ad hoc networks with MAC frame aggregation.
