A Multi-attribute Vertical Handover Algorithm Based on Adaptive Weight in Heterogeneous Wireless Network

As one of the key issues of users´ mobility management in next generation of heterogeneous wireless network, vertical handover has received extensive attention in academic and industrial circles. With the development of mobile terminals, mobile users can simultaneously run different types of applications, which have different requirements on network properties. Therefore, this article proposes an adaptive weight vertical handover algorithm, which can select the most suitable network as target handover network, according to the type of working application and the adaptive calculating weight vector to user´s preference. The simulation results show that the presented algorithm can not only automatically select access points that suit mobile users best, but also reduce the unnecessary handovers.
