Abstract :
In this paper, a novel vertical handover control algorithm, consisting of a throughput-based mapping function, QoS-based dynamic handover thresholds, and performance-based trigger timers, is proposed to resolve uncommon pilot problems, QoS requirements, and ping-pong effects, respectively. A numerical analysis is provided to evaluate the proposed algorithm in terms of the handover frequency and achievable throughput. The performance is further quantified by a simulation based on mixed of UMTS and WLAN systems
