| Summary: | 碩士 === 雲林科技大學 === 資訊工程研究所 === 96 === Broadband Fixed Wireless Access (BFWA) systems are a fixed point-to-multipoint (P-MP) broadband cellular networking solution operating at millimeter-wave frequencies. The P-MP BFWA systems are suitable for the high-density deployment of high capacity wireless access infrastructures but there are still difficulties in the operations of wireless systems such as the degradation of wireless link quality in rainy wide areas, routing issues in mesh topology, etc. In this thesis, we propose node architectures and a shortest path routing scheme for wireless Chordal Single Ring Network (CSRN) that is suitable for BFWA systems. The CSRN topology has the primary advantages of using the chordal links to shorten transferring paths of data packets and providing increased reliability compared to the original ring network due to its multiple routing paths. A BFWA system with the CSRN topology is an effective approach to overcome the limitations of P-MP BFWA systems. To guarantee data packets in CSRN routing with a shortest path and avoiding out-of-sequence packet delivery problem, we devise a new routing algorithm for the CSRN. With mathematical proof, our new routing scheme outperforms other routing schemes for networks based on the ring topology.
