由於通訊技術不斷的改進,無線網路已成為下一世代中最受歡迎的網路技術之一。 近年來,無線網路的通訊協定已迅速發展並提供給廣大的使用者們方便且彈性的無線服務。而在產界中,許多商品已經被設計並且銷售。研究人員和專家學者們也在研究如何改善無線路由的設定並增進其傳輸效率及增加頻寬的使用率。
透過網路電話(Voice over Internet Protocol, VoIP)這項技術已使得網路的存取比以前多了更多用途,在使用上也增添了更大的靈活性。然而,建立愈多的網路通訊,將會造成傳送的延遲而傳送時間也被拉長,封包遺失的比率也會增高。為了提供給無線網路一個良好的服務品質,在這篇文章中,我們提出了一個架構在IEEE 802.11e無線區域網路標準的網狀網路上維持網路品質的有效機制。這個機制不僅提供良好的傳送品質,並且增加通訊通道使用率。實驗結果顯示此機制比起IEEE 802.11b或是其他的方法更能改善系統效能。
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.
