碩士 === 國立中央大學 === 資訊工程研究所 === 89 === A mobile ad hoc network (MANET) is a characterized by multi-hop wireless links, absence of any cellular infrastructure, and frequent host mobility. This thesis investigates an on-demand, link-state, multi-path QoS (quality-of-service) routing protocol in a MANET, which is important for many real-time multimedia applications. The basic idea of the on-demand, link-state, multi-path routing protocol is to reactively collecting the link-state information from source to destination in order to dynamically construct a flow network, which is a network topology sketched from source to destination in a MANET. herefore, a multi-path QoS routing protocol is proposed by finding multi-path route in the destination under the CDMA-over-TDMA channel model, which satisfying a given bandwidth requirement. Existing works mainly try to exploit a uni-path from source to the destination. Destination accurately determines a QoS multi-path routing and replies to the source host. This greatly improves the success rate by means of searching the QoS multi-path routing. Performance analysis results demonstrates that our proposed protocol outperforms other protocols.
