  • 多媒體應用將主導未來無線通訊,它需要高資料率和具有多樣化的服務品質與不同話務型態的服務。為了提供無接縫式服務,蜂巢式網路之細胞必須具有足夠的資源提供遞交連線之用。因蜂巢式網路受到有限的頻道限制,如何對無線資源做有效管理,將是增進網路效能的一個關鍵因素。
    發展下一代的行動系統最具挑戰之課題是如何設計新技術於無線通訊資源管理和處理遞交的過程。根據無線多媒體網路的應用環境,本論文提出多樣化的頻道預留機制、遞交預測方法、及允入控制的運算法則。我們設計和分析新的頻道預留方案於下一代高速多媒體無線網路。在提出的方案中,我們利用動態調節的方式來預留頻道,以達成降低連線阻塞率、遞交阻塞率、及增加頻道利用,同時對於服務品質敏感的行動多媒體,亦能維持服務品質在一可接受的水準。
    除此之外,在無線隨意網路中,電源的管理是另一最具挑戰的問題。根據無線隨意網路的操作過程,路徑的選擇可分成三階段來處理:啟始、進行中及分開。選擇路徑的準則是根據路徑跳躍數、節點剩餘的電源門檻、及節點電源耗盡數的門檻。在提出的方案中,我們利用以階段為基礎的繞徑策略以達成各節點均勻地消耗電源,所以網路的使用期限增加和連線請求的失敗率減少。
    模擬結果顯示,在適當的參數選用下,我們提出的方案其相關效能的量測均勝過文獻中先前提出的方案。


    Future wireless communications will be dominated by multimedia applications that require high data rates and diversified services with different quality-of-service (QoS) and different traffic profiles. To provide seamless service in cellular networks, cells must provide sufficient resources for handoff connections. Due to the scarce radio resources in cellular networks, efficient management of these resources and mobility become a key factor in enhancing network performance.
    One of the most challenges for the development of next-generation mobile system is to design new technologies for wireless communication resource management and handling of handoff process. Based on the applied environments of multimedia wireless networks, diverse bandwidth reservation mechanisms, handoff prediction scheme, and admission control algorithms are presented in this thesis. We design and analyze novel bandwidth reservation schemes for next-generation high-speed multimedia wireless networks. In the proposed schemes, we use the dynamically adaptive approaches to reduce the connection blocking probability, connection dropping probability, and to increase the bandwidth utilization, while the quality-of-service guarantees can be maintained at an acceptable level for quality-of-service sensitive mobile in multimedia wireless networks.
    In addition, energy conservation is another one of the most challenging problems in wireless ad hoc networks. Based on the network operation process, path selection can be processed in three phases: initial, in-progress, and partitioned. The criteria of selecting a route is based on the number of hop count along the path, the threshold of remaining energy of terminals, and the threshold of the number of out-of-energy terminals. In the proposed schemes, we use the phase-based energy efficient routing strategy to consume energy evenly among terminals so that the network lifetime is maximized and the failure rate of connection requests is minimized.
    Simulation results show that our proposed schemes outperform the previously proposed schemes in the literature in terms of relative performance measures when proper parameters are chosen.
