碩士 === 國立臺灣大學 === 資訊工程學研究所 === 93 === The wireless mesh network (WMN) is a new broadband Internet access technology drawing significant attention these days. It provides an alternative technology for last-mile broadband Internet access. Through the services provided by the WMN, users can enjoy always-on (anytime and anywhere) communication even in an outdoor environment. However, the wireless multi-hop transmission may not support QoS requirements for voice. Hence, we develop a multi-path delivery method to transmit the voice packet. By using our multi-path adaptation method, we show that our method perform better than other multi-path methods, and can meet the several requirements simultaneously because our method takes the network state into consideration. From the results in different topologies, we can find that its high capacity. Finally, we can conclude that although our modified SCTP consume more bandwidth than UDP, it has substantial improvement for the QoS of VoIP. And it won''t cause the starvation of other users.
