碩士 === 國立清華大學 === 資訊工程學系 === 94 === Mobile IP (MIP) has been proposed by the IETF as the mobility management protocol in IP networks. However, MIP might cause long handoff latency and high end-to-end delay. In order to minimize the inefficiency in MIP, micro-mobility management protocols have been proposed. However, most of them consider the mobility management at IP layer only. Unlike other proposals, earlier we have proposed Fast Intra-Network and Cross-layer Handoff (FINCH) which considers the mobility management at both link and IP layers. Because of the cross-layer design, the performance improvement is significant. Normally, micro-mobility management protocols are used in infrastructure networks, which provide Internet access through access points in the range of single wireless hop. Some protocols have been proposed to integrate micro-mobility management protocols with ad hoc networks, which extend the range to multiple hops away from an access point. In this thesis, we propose the integration of FINCH with two types of ad hoc routing protocols, Destination-Sequenced Distance-Vector (DSDV) and Ad-hoc On Demand Distance Vector (AODV). We also adapt the ad hoc routing protocols into the cross-layer design. The performance of our design is evaluated by extensive simulation. Results show that the cross-layer design outperforms those without crossing layer. The FINCH could be used with different ad hoc routing protocols. It is a trade-off between different performance metrics.
