整合式服務網際網路與無線通訊是現今網路發展的兩大趨勢。為了讓使用者能夠方便地透過無線網路的環境,在網際網路上享受具有服務品質保證的整合式多媒體即時通訊服務,網路資源保留的機制是必要的。
在這一篇論文中,我們提出了一個經濟式的資源保留方法。其作法是透過區分對不同的使用者對於鄰近細胞資源的需求度不同下,提供了差異性資源預約等級給具移動性質的使用者,為的是要節省預先所需保留的資源。如此的區分方式可以更貼近使用者的資源預約需求,並可節省在鄰近細胞下不必要的資源保留,進而可以增加具有服務品質的連線數目,並改善整體的連線服務品質。
且本論文對於資源的使用上是採用靜態定價模式的索費方式來輔助該資源保留協定的運作,再加上去對原RSVP 信息做擴充,使得可以讓移動式使用者更準確知道什麼樣的預約等級較適合他們,來使得本文所提出經濟式的資源保留方法發揮地更有效率。
且透過簡單的數學分析來證明我們所提的經濟式資源保留方法架構比對鄰近所有細胞去做預約的方法(All Neighboring Cells Reserved in advance, ANCR) 去做比較,是能夠容納較多具有品質保證的使用連線數 目,並改善整體的無線網路服務品質。
透過軟體的模擬,在觀察時間內我們比較了其所能完成品質保證連線的總數、新進通話和交遞通話的阻隔率、頻寬資源的利用率、並衡量服務等級的好壞,我們發現這樣的資源保留方法確實可以改善整體的網路品質。且此方法可以應用在當網路業者依資源使用量方式來計費時,平均而言可以減少使用者在網路服務上的付費成本。

The resource reservation mechanism is essential for QoS provisioning in wireless networks. To support mobility with QoS guarantees, mobile hosts need to reserve resources in advance at locations where the hosts may visit next. Previous works always try to reserve resources in all neighboring cells for any mobile hosts with guaranteed requirements. However, these schemes do not consider that different mobile hosts can have different QoS requirements when they experienced handoff process, and therefore underutilize the network resources. In this thesis, we present an Economic Resource Reservation Scheme (ERRS) to manage the scarce resources efficiently in wireless networks. The ERRS is based on a static pricing plan for resource usage. The ERRS scheme differentiates QoS requirements of mobile hosts in neighboring cells. The ERRS allows a mobile host to detect and decide whether to reserve required resources in neighboring cells beforehand. The proposed scheme is simulated and is compared with the conventional ANCR (all neighboring cells reserved in advance). The results of mathematical analysis and simulations indicate that the ERRS can accommodate more numbers of active guaranteed flows and improve the QoS of connections in wireless networks.
