The AUTOSAR(AUTOmotive Open System ARchitecture) is an open software platform for automotive. The AUTOSAR contains the modules of FlexRay that is the next generation automotive network protocol. We have developed the modules including FlexRay State Manager, FlexRay Transport, FlexRay Interface, FlexRay Transceiver Driver and FlexRay Driver based on the standard of the module. This thesis presented not only the result of development but the result of design and implementation. And the developed modules were ported to the microcontroller board and verified.

There has been a continued increase in the complexity of software equipped with wireless mobile devices, due to the introduction of new device functionality and services via network connection. The increasement expected to be accelerated by convergence of telecommunication and broadcasting, and proliferation of telematics and home networking services using wireless mobile devices. The higher the complexity of mobile device software, the higher the necessity of management for the software. As for the global standard of mobile device management technology, OMA DM has been widely adopted by device manufacture and expected to be accelerated its adoption. In this paper, we present a development result of mobile device software release management system ThinkSync DM SoftMan. The implementation details of ThinkSync DM SoftMan are provided in implementation architecture and its working scenario based on the design of ThinkSync DM SoftMan that is summarized in this paper as our previous work. The conformance and performance test of the system are presented.

SyncML is an open standard data synchronization protocol proposed by OMA(Open Mobile Alliance). In this paper, a Session Handler module, one of major modules for developing SyncML data synchronization clients, and a client User Setup program are designed and implemented. The Session Handier Module controls communication sessions, generates header parts of messages exchanged, and determines the legitimacy of incoming messages. In order to justify normal operations of the Session Handler module and the client User Setup program implemented In this paper, they are ported to a Zaurus PDA, which runs on LINUX operating system. In addition, data synchronization operations are performed between the PDA and a Synthesis sever, whose SyncML data synchronization operation is certificated by OMA, Wireless Internet International Standard Forum.

The WAP 2.0 system is a newly proposed wireless communication system by the WAP Forum for interoperability across Internet environment and the system takes charge of communication between WAP terminals and existing origin Web servers. The purpose of this paper is 1) to construct a WAP 2.0 proxy proposed by the WAP Forum and 2) to improve the WAP Proxy in order to increase communication efficiency between wired and wireless communication objects. The Improved WAP proxy constructed in this study provides links between wired and wireless communication environments using the split-TCP concept. However, unlike the split-TCP connection, The improved WAP proxy maintains TCP`s end-to-end semantics and reduces overhead by avoiding operations as much as possible on the upper protocol layer. In addition, The improved WAP proxy supports SACK(Selective Acknowledgement ) option and Timestamp option for speedy re-transmission which leads to reduction of performance degradation. After constructing the improved WAP proxy under Linux environment, experiments have been taken. The experimental results show that, compared with the experiments when a WAP proxy proposed by the WAP Forum is used, both data transmission delay time and data transmission size decrease to show that communication efficiency is increased. In particular, as packet missing ratio Increases, data transmission size decreases, which demonstrates that the improved WAP proxy is very effective for performance improvement in wireless communication environment.
