下一代無線網路已經被認為是一個整合網際網路以及各種通訊網路的全IP網路，本篇論文主要探討在下一代無線網路中的「行動管理」與「電能效益」兩項重要議題。
首先，我們深入研究了各種行動管理協定，並且提出了一套「可重設定架構暨行動管理平台」(Reconfigurable Architecture and Mobility Platform, RAMP)，在此平台中，使用者與網路端能透過協議動態執行各自所需要的行動管理協定，而我們從數學分析、網路模擬以及實驗平台數據都驗證了此平台的可行性以及各種效能。此外，電能效益一直是無線網路中的一項重要議題，尤其下一代無線網路的高速資料傳輸更會快速消耗行動裝置的電能，在論文中我們研究並量化比較了3GPP與3GPP2的節能機制，而我們提出的分析模型更可以提供一個可行的方法作為節能機制中參數調校的依據。
WiMAX被認為是下一代無線網路重要標準技術之一，經由我們在行動管理與電能效益中的研究，我們在WiMAX行動環境中提出一套「快速內部網路跨層換手協定」(Fast Intra-Network and Cross-layer Handover, FINCH)來支援快速且有效率的換手機制，同時，此協定也支援休眠機制以達到節電的目的。數學分析與網路模擬驗證了提出的協定可以有效減低Mobile IP換手以及傳輸兩端的延遲，因此特別適用於高速移動下存取即時性資料的情境，而這也正是WiMAX在下一代無線網路中的重要應用。此外，提出的FINCH協定也能適用於其他一般性的無線系統，因此可以有效應用在下一代整合性的無線網路。

Next generation wireless networks are expected to be all-IP networks which integrate Internet and the diverse cellular networks. In this thesis, we focus on the two critical issues in next-generation all-IP wireless networks: mobility management and energy-efficiency.
As the first step, we study the mobility management protocols and propose Reconfigurable Architecture and Mobility Platform (RAMP). The proposed RAMP allows both mobile users and network operators to negotiate and execute their desirable protocols dynamically. Results from the analytic models, network simulations, and testbed experiments then verify the performance of RAMP. Moreover, energy efficiency is also crucial to wireless networks, especially for the high-speed data transmissions in next-generation wireless systems. We evaluate and quantify the energy conservation mechanisms in 3GPP and 3GPP2. The proposed analytic models then provide a practical method to configure the proper timer lengths.
WiMAX is one of the promising standards for the next-generation wireless access networks. Based on the study of energy efficiency and mobility management, we propose the Fast Intra-Network and Cross-layer Handover (FINCH) protocol to support fast and efficient handover in the mobile WiMAX. Paging extension for FINCH also enhances the energy efficiency of the mobile WiMAX devices. Analytic and simulation results demonstrate that FINCH can reduce not only the handover latency but also the end-to-end latency for MIP. FINCH is designed for real-time services in frequent handover environment, which is important for future mobile WiMAX networks. In addition, FINCH is a generic protocol that is especially beneficial for the integration of the heterogeneous networks in next-generation wireless networks.
