We present a study on the effects on a mobile system's energy efficiency of enhancing, with partial reliability, our energy efficient TCP variant (E2TCP) (see Donckers, L. et al., Proc. 2nd Asian Int. Mobile Computing Conf. - AMOC2002, p.18-28, 2002). Partial reliability is beneficial for multimedia applications and is especially attractive in wireless communication environments. It allows applications to trade a controlled amount of data loss for a higher throughput, lower delays, and lower energy consumption. In the design of E2TCP, we provide solutions to four problem areas in TCP that prevent it from reaching high levels of energy efficiency. We have implemented a simulation model of the protocol, and the results show that E2TCP has a significant higher energy efficiency than TCP.
