“…One of the most important issues involved in the heterogeneous wireless networks is making a decision to choose "the best network" for users' access. Such a network selection decision can be referred to the "Always Best Connected (ABC)" concept [7]. A decision-making entity needs not only to guarantee the satisfaction perceived by each mobile user, but also to ensure the fairness and efficiency of network resource allocation among a large amount of mobile users.…”

With the increasing demands for vehicle-to-vehicle and vehicle-to-infrastructure communications in intelligent transportation systems, new generation of vehicular telematics inevitably depends on the cooperation of heterogeneous wireless networks. In heterogeneous vehicular telematics, the network selection is an important step to the realization of multimode communications that use multiple access technologies and multiple radios in a collaborative manner. This paper presents an innovative network selection solution for the fundamental technological requirement of multimode communications in heterogeneous vehicular telematics. To guarantee the QoS satisfaction of multiple mobile users and the efficient utilization and fair allocation of heterogeneous network resources in a global sense, a dynamic and self-adaptive method for network selection is proposed. It is biologically inspired by the cellular gene network, which enables terminals to dynamically select an appropriate access network according to the variety of QoS requirements and to the dynamic conditions of various available networks. The experimental results prove the effectiveness of the bioinspired scheme and confirm that the proposed network selection method provides better global performance when compared with the utility function method with greedy optimization.Index Terms-Heterogeneous wireless networks, vehicular telematics, intelligent transportation systems, quality of service, attractor selection model.

“…This selection is based on always best connection principle. The concept of always best connected (ABC) for continuous flow of information is explained in the study of Louta and Bellavista that explains how in order to support best service always best connection is required. From best connection, network selection comes into existence.…”

Summary The growth of wireless communication toward fifth generation will lead to the existence of number of access technologies to provide seamless connectivity and form heterogeneous network environment. Earlier, there was single access technology to run applications, but 5G will have heterogeneous network environment and provide separate network for each application. As compared with 4G, 5G will provide increase in data rate, decrease in delay, increase in quality of service, and so on because of its various enabling technologies. Therefore, for each application, selection of best access network via its enabling technology is an important task. This selection is done either at user terminal side or at network operator side by combining preferences for network attributes and network parameters. In this paper, to enjoy 5G, selection is done in a heterogeneous networks environment for enabling technologies like device‐to‐device communication, spectrum sharing, enhancing quality of experience, energy efficiency, and so on. This selection is done via optimization techniques for a fixed duration video clip that is to be transmitted from a device running low in battery. The selection environment composed of UMTS, WLAN1, and WLAN2 as available networks. The simulation results show that the network selected for each enabling technology supports various features of 5G. Also, error analysis of selection results is done using confidence interval estimate at 90%, 92%, and 95% confidence level. From results obtained, it is seen that different optimization techniques used to access network for different enabling technologies (providing 5G features) prove to be useful for future 5G network.

“…Based on previous formulations, we study the network selection issue of the vertical handoff in this section. We assume that users are selfish, they will select access points in the always-best-connected (ABC) way [28] if allowed. That is, users always choose the access points which have the best performance as their new access points.…”

“…In this section, we provide the performance evaluation of our S-DNVH scheme. We compare the proposed scheme with two typical existing schemes: the ABC scheme [28] and the SASHA [15] under various network conditions. The concerned performance metrics are the number of handoffs, total throughput and the user served ratio.…”

A novel software‐defined networking approach for vertical handoff in heterogeneous wireless networks

We propose a novel vertical handoff scheme with the support of the software-defined networking technique for heterogeneous wireless networks. The proposed scheme solves two important issues in vertical handoff: network selection and handoff timing. In this paper, the network selection is formulated as a 0-1 integer programming problem, which maximizes the sum of channel capacities that handoff users can obtain from their new access points. After the network selection process is finished, a user will wait for a time period. Only if the new access point is consistently more appropriate than the current access point during this time period, will the user transfer its inter-network connection to the new access point. Our proposed scheme ensures that a user will transfer to the most appropriate access point at the most appropriate time. Comprehensive simulation has been conducted. It is shown that the proposed scheme reduces the number of vertical handoffs, maximizes the total throughput, and user served ratio significantly.A demonstrationof the wireless communications and mobile computing class file L.
