The main challenge in the development of future wireless communication systems is to provide users with a wide range of services across different radio access technologies through a single mobile node, while maintaining the quality of service requirements. However, design varieties can lead to service degradation as the mobile node move across different systems. The integration of heterogeneous networks will be a trend for next generation networks. For supporting seamless mobility and ensuring the ongoing session not to be disrupted from one access network to another, it is necessary to reduce total handover time and service disruption time. In this thesis, we try to integrate IEEE 802.11 WLANs and IEEE 802.16 WMANs, using the new standard developed by IEEE standard group. IEEE 802.21 is also called Media Independent Handover (MIH) which provides a framework for facilitating homogeneous handover and heterogeneous handover. First, we describe handover procedure of IEEE 802.21 and compare it with the completed method from the literature. Second, we discuss our proposed scheme using FMIPv6 to handover across networks and use mathematical analysis for different schemes. Last, we perform experiment on the NS2 simulator and compare it with the other existed methods from the literatures. Chen, Yaw-Chung 陳耀宗 學位論文 ; thesis 47 en_US |
