Summary: | 碩士 === 國立中正大學 === 資訊工程所 === 94 === In this thesis, we propose a new quality-of-service (QoS) routing protocol for mobile ad hoc network (MANET) using directional antenna. This scheme offers a bandwidth routing protocol for QoS support in a MANET using directional antenna, where the MAC sub-layer adopts the CDMA-over-TDMA channel model. The QoS on-demand routing protocol determines the end-to-end bandwidth calculation and bandwidth allocation from a source node to a destination node. Some cross links with different sources and destination nodes, called as shoelace, are existed and identified in this work. Due to the directional antenna property, these cross links (shoelace) can simultaneously transmit data without any data interference. This investigation develops a shoelace-based QoS on-demand routing protocol by identifying shoelaces in a MANET to more easily construct a QoS route which satisfied a given bandwidth requirement. With the identified shoelaces, our shoelace-based scheme offers a higher success rate to construct a QoS route. The shoelace-based route from a source to a destination is a route whose sub-path is constructed by shoelace structure. This improves the success rate by means of multi-path routing. Finally, simulation results demonstrate the performance achievements our proposed protocol in success rate, throughput, wireless medium utilization, and transmission latency.
