An Analysis of Energy Consumption on ACK plus Rate Packet in Rate Based Transport Protocol

TL;DR

This paper analyzes the energy consumption of ACKplusRate packets in rate-based transport protocols, revealing higher energy use in low mobility networks and proposing Dynamic Rate Feedback to improve efficiency.

Contribution

It introduces Dynamic Rate Feedback (DRF), a novel technique that reduces energy consumption by sending ACKplusRate only when significant rate changes occur.

Findings

ACKplusRate transmission consumes more energy in low mobility networks

DRF reduces energy consumption by limiting ACKplusRate transmissions

Simulation shows DRF outperforms traditional methods in energy efficiency

Abstract

Rate based transport protocol determines the rate of data transmission between the sender and receiver and then sends the data according to that rate. To notify the rate to the sender, the receiver sends ACKplusRate packet based on epoch timer expiry. In this paper, through detailed arguments and simulation it is shown that the transmission of ACKplusRate packet based on epoch timer expiry consumes more energy in network with low mobility. To overcome this problem, a new technique called Dynamic Rate Feedback (DRF) is proposed. DRF sends ACKplusRate whenever there is a change in rate of (plus or minus) 25 percent than the previous rate. Based on ns2 simulation DRF is compared with a reliable transport protocol for ad hoc network (ATP)
