| Summary: | 碩士 === 東海大學 === 資訊工程與科學系 === 95 === Due to incessant advancement of communication technology, wireless networking has become one of the most popular techniques in next generation of network area. Recent wireless network protocols have evolved swiftly to provide with extensive and flexible wireless services to users. Lots of products have been designed and marketed. Many researchers have studied how to improve routing efficiency and channel utilization of wireless networks.
The Voice over Internet Protocol (VoIP) supported by wireless technology has made Internet accesses more versatile and flexible than before. However, the more sessions established for communication, the longer the transmission delay and the higher the packet dropping rate. In this paper, an efficient scheme developed on the IEEE 802.11e standard for mesh network is proposed. It not only provides qualified transmission, but also increases communication channel utilization. Experimental results show that this approach significantly improves a system’s throughput as compared with those developed on 802.11b and other schemes.
