An Intelligent Vertical Handoff Decision Algorithm for Heterogeneous Wireless Networks

Abstract

Abstract. The next generation wireless systems will consist of heterogeneous networks from cellular, Wi-Fi, WiMAX to other emerging access technologies. Vertical handoff occurs when a mobile terminal decides to switch between networks. One of the challenging problems during vertical handoff is the selection of an optimal network that maximizes end users satisfaction. This paper presents an intelligent vertical handoff decision algorithm that selects the target network based on the traffic class of the mobile user. The algorithm uses two modules, to estimate the handoff requirement and to select the optimal network. These modules utilize Fuzzy Logic and Genetic algorithm to make an intelligent vertical handoff decision.

A prompt CNN-FL model based on multi criteria for a smart vertical handoff in heterogeneous system

“…Anupama carries out an intellectual VHDP that prefers the target heterogenic network depend on mobile user traffic. (Anupama et al , 2014) The algorithm evaluated by exploiting the two modules, one to appraise the handoff condition and second to choose the ideal system by FL with genetic algorithm to stay on an insightful VHDP.…”

Optimizing Resource Allocation for Secure SDN-based Virtual Network Migration

“…For example, Wang et al proposed in [32] a Continuous Time Markov Decision Process to optimize the revenue generated by the cloud infrastructure by determining the optimal CPU power depending on client requests and energy consumption. In [33], the authors propose a discrete time MDP where, at each time point, the user will have to choose whether he wishes to keep using the current networking technology or switch to another (e.g., from WLAN to 4G).…”

Adaptive Decision of Wireless Access Network for Higher User Satisfaction

“…The practical use of vertical handover rapidly grew as mobile devices like smartphones were widely used. References [4][5][6][7] provided various intelligence-based solutions for proper vertical handover between macrocells and supplement access points such as pico/femtocells and Wi-Fi APs. They used various parameters related to link quality of each access point, such as signal strength, bit error rate, bandwidth size, and jitter level.…”
