Comparative analysis of ADTCP and M-ADTCP: Congestion Control Techniques for improving TCP performance over Ad-hoc Networks

TL;DR

This paper compares ADTCP and M-ADTCP congestion control techniques for TCP in mobile ad-hoc networks, proposing a modified protocol where the receiver detects network status and provides feedback to improve performance.

Contribution

It introduces M-ADTCP, a novel congestion control method where the receiver detects network conditions and informs the sender, enhancing TCP performance over ad-hoc networks.

Findings

M-ADTCP improves congestion detection accuracy.

The proposed method is compatible with standard TCP.

Enhanced TCP performance in mobile ad-hoc networks.

Abstract

Identifying the occurrence of congestion in a Mobile Ad-hoc Network (MANET) is a major task. The inbuilt congestion control techniques of existing Transmission Control Protocol (TCP) designed for wired networks do not handle the unique properties of shared wireless multi-hop link. There are several approaches proposed for detecting and overcoming the congestion in the mobile ad-hoc network. In this paper we present a Modified AD-hoc Transmission Control Protocol (M-ADTCP) method where the receiver detects the probable current network status and transmits this information to the sender as feedback. The sender behavior is altered appropriately. The proposed technique is also compatible with standard TCP.
