2004 Proceedings of the 7th ACM international symposium on Modeling, analysis and simulation of wireless and mobile systems - MSWiM '04  
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.  ...  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  ...  CONCLUSIONS Previous research has shown that the effect of hidden ter-minals in MANETs due to interference can cause considerable degradation to TCP performance.  ...

M. Sivaram, V. Porkodi, Amin Salih Mohammed, V. Manikandan, N. Yuvaraj
2019 IEEE Access  
The Mobile Ad-hoc Networks (MANETs) are often visible to the exposed terminal problem and hidden terminal problem, which exist due to non-transitivity in media access control schemes.  ...  Hence, in this paper, the quality of service (QoS) is improved by enhancing the capability of the DBTMA for better network service in the MANETs.  ...  This occurs due to interference in transmissions from node D. This leads to the problem of a hidden terminal between the nodes in the network. E.  ...
