Reducing the degrading effect of hidden terminal interference in MANETs
Stylianos Papanastasiou, Lewis Mackenzie, Mohamed Ould‐Khaoua · 2004
A number of recent research studies have explored ways to improve TCP throughput in IEEE 802.11 mobile ad hoc networks. In particular, hidden terminal effects caused by interference have been shown to degrade TCP performance and have been dealt with, in previous work, by restricting the maximum congestion window size. We have pursued an alternative approach and have developed a TCP variant which adjusts the sending rate increase to achieve competitive goodput for TCP connections. In this paper, we demonstrate that a slower sending rate increase during the congestion avoidance phase of TCP leads to improved performance for TCP Reno while eliminating the negative effects inherent in restricting the maximum congestion window size. A performance comparison against existing solutions under various mobility conditions is also included.
