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

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 ACK+Rate packet based on epoch timer expiry. In this paper, through detailed arguments and simulation it is shown that the transmission of ACK+Rate 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 ACK+Rate whenever there is a change in rate of ±25% than the previous rate. Based on ns2 simulation DRF is compared with a reliable transport protocol for ad hoc network (ATP) .
