“…The work in [9] is one of many studies with the general context of CRRM [1,6,7,[10][11][12][13][14], all of which advocate and verify that jointly managing the resources of the different access technologies would result in both higher operator profitability and user satisfaction. Such studies further considered various attributes for both networks and users, including static and dynamic characteristics.…”

Common Radio Resource Management techniques have shown great promise in both enhancing network operation and user satisfication. Such gains are achieved through the joint management of the individual access technologies in a Heterogeneous Wireless Network. The objective of this work is to expand on the existing body of work to accommodate heterogeneity not just at the traditional access‐network level but to other connectivity modes such as dynamic spectrum access. Such modes affect operator profitability in both the long and short terms. Specifically, we explore the design of a cost‐management model that adapts to the short‐term variability in connectivity costs. We also display the operational aspects and effectiveness of this functionality through both simulation and an analytical model. Copyright © 2012 John Wiley & Sons, Ltd.

Current vehicular communication systems experience from nonflexible and costly devices, complicated control-plane protocols, and vendor-specific configuration interfaces. In the next generation vehicular communication, a mobile device (MD) will be installed on a car capable of accessing multiple services from different networks. So heterogeneous networks (HetNets) may play a vital role in vehicular communication. Despite heterogeneity, flawless connectivity between different systems is a basic need of the travellers. The key challenge for seamless connectivity is the design of a vertical handover (VHO) scheme.We claim that software-defined networking (SDN) can make things easier in the design and supervision of VHO in vehicular HetNet. The proposed method maximizes the HetNet utilization with lesser handover by balancing the load among the HetNets. Simulation results performed in MATLAB justified that this novel architecture with proper VHO technique boosts the performance by balancing the load, reducing unnecessary VHO, etc. Performance is analyzed by considering four studies, ie, handover served ratio (HSR), on board units (OBUs), OBU served ratio (OSR), and total throughput and total capacities of road side units (RSUs) to serve handover demands from OBUs. It is observed that the HSR increases rapidly as the number of OBUs increases, which indicates almost all the handover requested OBUs are allocated resources by a connected RSU. We also studied the served total throughput by considering VHO with SDN, without SDN in the average case and without SDN in the best case, and it is observed that with SDN as a central controller, the total OSR and total throughput is increased.

As an outcome, the vehicular communication scenery will continue to vary for the estimated outlook. Building heterogeneity is an important aspect for service providers and mobile device companies to deal with.

“…A heterogeneous wireless network allows network operators to combine the complementary advantages of individual RATs, thus paving a way for improved quality of service (QoS) provisioning and increased revenue (Lopez-Benitez and Gozalvez, 2011). In a heterogeneous wireless network, subscribers with multi-interface (multimode) terminals can toggle between different RATs and select the RAT that best suits the characteristics and requirements of their applications.…”
