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 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)Comment: 7 pages IEEE format, International Journal of Computer Science and Information Security, IJCSIS 2009, ISSN 1947 5500, Impact Factor 0.423, http://sites.google.com/site/ijcsis
