Anna Maria Vegni,Esposito +1 more
TLDR
An analytical model is presented in support of a novel vertical handover algorithm that uses the vehicle’s speed as crucial input and overcomes, under the assumptions, network performance of recent related works.Abstract:
Although Vehicular Ad hoc Networks are emerging as a novel paradigm for new classes of secure and safety services, supporting seamless connectivity remains a challenge, due to the high vehicle speed, and the nonhomogeneous nature of the network infrastructure. In this work we shall present an analytical model in support of a novel vertical handover algorithm that uses the vehicle’s speed as crucial input and overcomes, under our assumptions, network performance of recent related works. We support our initial results with a simulation study.read more

On modeling speed-based vertical handovers in vehicular networks: “Dad, slow down, I am watching the movie”
TL;DR: This work proves the counterintuitive result that in vehicular environments, even if a candidate network has significantly higher bandwidth, it is not always beneficial to abandon the serving network and introduces an analytical model for a vertical handover algorithm based on vehicle speed.
