| Summary: | 碩士 === 國立東華大學 === 資訊工程學系 === 95 === The goal of this thesis is to research the Network Mobility architecture and applications in the Wireless LAN environment, also develop the Embedded Linux based Mobile Router with Network Mobility architecture and functions. There are three main parts in the thesis: the research of Network Mobility application and architecture, Embedded Linux for Network Processor and Developing Embedded Linux based Mobile Router. By doing so, it promotes the Mobile IP technology and the foundation of Network Mobility in the future Wireless LAN environment. Combing the characteristics and advantages of Open Source Embedded Linux, users can access Internet services anytime, anywhere and any space. The world of ubiquitous computing and high bandwidth Internet access will come true soon.
This thesis finished Mobile Router architecture, definition of interfaces, and implementation on Embedded Linux System. Through some related works and standardization of Mobile Router and Mobile IPv6, the operating architecture and module definition of Mobile Router are finished and its performance is analyzed in several aspects.
In traditional Mobile IP mechanism, every Mobile Node has to process the hand off and registration to its Home Agent and each Access Router by itself. This mechanism will have better performance while the number of Mobile Nodes is small. However, if many Mobile Nodes hand off at the same time in conveyances, there will be many registration packets on the Mobile Network and decrease the performance. A Mobile Router can process hand off progresses for many Mobile Nodes at a same time. If there are a lot of Mobile Nodes under the Mobile Router, the performance will increase obviously.
This thesis will analyze the embedded Mobile Router with Round-Trip Time, Hand off Latency and mathematical aspects. And use ICMP packets to compare with traditional Mobile IPv6 and Mobile Router established on PC, to indicate the advantages of embedded Mobile Router in the future.
