Abstract: Heterogeneous network security is a prime concern in the era where billions of human beings and physical devices will get connected through next-generation technologies like millimetre-wave wireless, the internet of things, artificial intelligence and machine learning. Higher bandwidth in the millimetre range will help to achieve seamless connectivity and tens of gigabits per second data rate. In femtocells, handoff security will play a vital role to avoid call drops. This article focuses on how new handoff security algorithm deployed in the femtocells network by a method that uses Call Admission Control protocol and UMTS technology. Call admission control protocol gives variable quality of services by efficient utilisation of network resources and available bandwidth. The number of handoffs and probability of call drops is less when the user moves from femtocells to macro-cells. Dynamic threshold time reduces number of handoffs and improves handoff security.

Keywords: femtocells; handoff; call admission control; HetNet security; millimetre-wave; UMTS; call drop probability; femtocell access point; handoff threshold; signal to interference plus noise ratio.
