Abstract:A new generation handheld computer is under development in the Moby Dick project. Because of the desired functionality and performance, the energy consumption will be the limiting factor for this handheld. Wireless communication will also be an important factor in the project, which makes an energy-efficient transport protocol, compatible with TCP/IP, desirable. This thesis describes the design of such an energy-efficient transport protocol for mobile wireless communication. However, not much research has yet been done on the energy efficiency of transport protocols. First metrics were developed to measure the energy efficiency of transport protocols. These metrics were used to study the performance of TCP/IP on wireless links carefully. Four problem areas were defined that prevented TCP/IP from reaching high levels of energy efficiency. For these problem areas, solutions were proposed and their feasibility was examined. The results of this study were used to design E2TCP. A simulation model of this proposed energy-efficient transport protocol has been implemented and was subject to a thorough evaluation. The results show that E2TCP not only has a higher energy efficiency than TCP/IP, but it also manages to outperform TCP/IP on more traditional performance metrics: throughput and latency.
