A Policy-Based Vertical Handover System
نویسندگان
چکیده
The integration of different wireless transmission technologies provides several opportunities to perform load control and to optimize the Quality of Experience (QoE) of the end user. However, several problems occur when integrating these technologies. Each technology has its strengths and weaknesses in certain areas and several different approaches have to be applied to measure the performance. The contribution of this work is a proposal of a combined WLAN-UMTS network. We introduce three different policies on which we base the vertical handover decision, the load in the cell, Quality of Service (QoS) constraints, and user mobility. Simulation results illustrate how the policies are applied.

A cost-based approach to vertical handovers’ management
To implement seamless mobility inside an integrated, multiple (e.g. GPRS/WiFi) access system, a vertical handover policy has to be devised. This is usually done at the mobile terminal, allowing it to be customized from an end-user’s perspective, in order to fit individual needs/preferences. We propose a new approach in taking vertical handover decisions, which are not anymore exclusively based ...

متن کاملAn Optimal Vertical Handover Strategy for Vehicular Network based on IEEE 802.21 MIH standards
Media Independent Handover (MIH) is a standard proposed by IEEE 802.21 working group to facilitate vertical handover support between heterogeneous wireless networks. Currently, the implementation of the IEEE 802.21 standard supported in ns2, provided by National Institute of Standards and Technology (NIST) considers only the signal strength as a parameter to determine the destination network. S...
