Dynamic Dwell Timer for Hybrid Vertical Handover in 4G Coupled Networks

Cellular networks coupled with wireless local area networks would be very common in the next- generation wireless environments. This integration would be made possible by employing techniques of vertical handover across different radio access networks. Finding precise timing to carry out vertical handover is an important problem and is the topic of this research work. We propose a hybrid vertical handoff (HVH) initiation by intelligent fusion of adaptive threshold, signal trend detection and variable width dwell timer. Simulation studies have shown that our proposed approach results in a better vertical handoff experience as compared to existing techniques.
