【 摘 要 】

The growing consumer's demand leads a great access to communication services anywhere and at anytime. It has started to accelerate the development of technologies that would allow for the integration of various Wireless Access Technologies. With regard to vertical handoff performance, there is a critical need for developing algorithms for connection management and optimal resource allocation for seamless mobility. This study proposes a novel Vertical Handoff Decision Making Algorithm (VHDMA) based on analytic multi-objective optimization. The multi-objective cost function involves transmit power of Mobile Terminals (MTs), outage and throughput over Access Points (APs)/Base Stations (BSs). The proposed algorithm lowers the barriers and jointly optimizes all the required objectives. The results showed that the Multi-Objective (MO) optimization has the advantages of optimizing over different and conflicting objectives jointly.
