“…In consequence, there should be a tool for seamless authorization, authentication, and channel access based on the personalized key. The work on vertical handover, or in general media-independenthandover may be treated as the baseline for further research on this topic [53][54][55].…”

The era of 5G networks is approaching fast and its commercialization is planned for 2020. However, there are still numerous aspects that need to be solved and standardized before an average end-user can benefit from them on a daily basis. The 5G technology is supposed to be faster, provide services of higher quality, and better address the evolving needs of customers. As a consequence, 5th generation network needs to be implemented with efficiency and flexibility in mind, and thus, it fits well with the concepts of virtualization which enable sharing of physical resources among different operators, services, and applications. In this paper, we present an overview of these concepts, resulting from our discussions, i.e. between academic researchers and active network architects, and we describe the operation of a model that is most likely to emerge in such a complex network environment.

“…When having multiple interfaces available, an important decision to make is when to change from one interface to another, which is called VHO. Protocols such as 802.21 or 802.11u uses VHO for seamless handover between networks of different types [25]. For example, when moving out of the coverage area of a WLAN access point (AP), the throughput typically goes down with the distance to that AP.…”

Predicting expected TCP throughput using genetic algorithm

Predicting the expected throughput of TCP is important for several aspects such as e.g. determining handover criteria for future multihomed mobile nodes or determining the expected throughput of a given MPTCP subflow for load-balancing reasons. However, this is challenging due to time varying behavior of the underlying network characteristics. In this paper, we present a genetic-algorithm-based prediction model for estimating TCP throughput values. Our approach tries to find the best matching combination of mathematical functions that approximate a given time series that accounts for the TCP throughput samples using genetic algorithm. Based on collected historical datapoints about measured TCP throughput samples, our algorithm estimates expected throughput over time. We evaluate the quality of the prediction using different selection and diversity strategies for creating new chromosomes. Also, we explore the use of different fitness functions in order to evaluate the goodness of a chromosome. The goal is to show how different tuning on the genetic algorithm may have an impact on the prediction. Using extensive simulations over several TCP throughput traces, we find that the genetic algorithm successfully finds reasonable matching mathematical functions that allow to describe the TCP sampled throughput values with good fidelity. We also explore the effectiveness of predicting time series throughput samples for a given prediction horizon and estimate the prediction error and confidence.

“…Many VHO approaches have been proposed in the literature applied with FL [25,26,27], [28,29,30,31,32,33,34,35] which have been surveyed in [36] and [22], respectively. There are also another VHO approaches have been proposed in [37,38,39,40].…”

The Next Generation Wireless Systems (NGWSs) consists of heterogeneous wireless access networks such as UMTS, Wi-Fi, WiMAX and LTE where Mobile Users (MUs) can access these technologies and services using a single device. This device is equipped with multiple radio interfaces include devices capable of supporting multiple Radio Access Technologies (RATs) by incorporating several interface cards and appropriate software for switching between multiple access systems (Vertical Handover (VHO)). The Access Network Selection (ANS) regarding the transferring between different RATs is based on network conditions, mobile conditions, user preferences, Quality of Service (QoS) requirements and service cost. This paper overviews VHO approaches proposed in the literature and classify them into three categories based on ANS methods for which their characteristics are presented. Finally, a conclusion about who is a dominant ANS method for seamless VHO is given.
