“…Recently, more attention has been given to user association and load balancing problems in heterogeneous RANs (e.g., LTE/WiFi) [15], [16], [17], [18], [19], [20], [21]. Reference [15] suggests an energy-efficiency driven load balancing strategy.…”

“…The authors conclude that multi-homing has better load balancing capabilities. A QoS-based algorithm is proposed in [20] for vertical handover in LTE/WiFi networks. Handovers are triggered when the QoS score for a certain wireless users is going below a certain threshold.…”

“…Also, the distance of the closest AP (i.e., the AP that provides the best channel condition to the client) is stored in the cls ap dis variable. The candidate list is then updated, adding also the candidate eNBs (lines [16][17][18][19][20][21][22][23][24]. Notice that after finding valid eNB candidates by checking the condition in line 18, like in the case of the ILP-based algorithm, it is checked whether the ratio of the distances between each candidate eNB and the closest candidate AP is less or equal β enb (line 19).…”

WiFi networks are known to be a cost-efficient traffic offloading solution for mobile networks. The Multi Access Packet Data Network Connectivity is a feature introduced in LTE Release 10 in order to allow users to be simultaneously connected to multiple radio access networks (RAN). Although this feature brings many advantages, such as the possibility to implement QoS-based traffic steering, it poses also many challenges, one of which is distributing traffic among the two radio access technologies. In this paper, we propose a trafficaware user association algorithm for heterogeneous LTE/WiFi RANs. The proposed algorithm is formulated as an Integer Linear Programming (ILP) problem jointly optimizing user association and resource allocation. A heuristic is also proposed in order to address the scalability issues of the ILP-based algorithm. Numerical simulations are used in order to compare the proposed approaches. Finally, we implemented and tested the heuristic in small-scale testbed using the 5G-EmPOWER platform.

“…For both cases, the aim of our video surveillance system is to mitigate the adverse effects of real time video streaming service disruptions. In the same way, the smart phone of the guard must need to do vertical handover [ 32 ] between LTE and WiFi (or viceversa). In this case, the wireless network must implement rapidly the handover processes.…”

Low-cost video surveillance systems are attractive for Smart Home applications (especially in emerging economies). Those systems use the flexibility of the Internet of Things to operate the video camera only when an intrusion is detected. We are the only ones that focus on the design of protocols based on intelligent agents to communicate the video of an intrusion in real time to the guards by wireless or mobile networks. The goal is to communicate, in real time, the video to the guards who can be moving towards the smart home. However, this communication suffers from sporadic disruptions that difficults the control and drastically reduces user satisfaction and operativity of the system. In a novel way, we have designed a generic software architecture based on design patterns that can be adapted to any hardware in a simple way. The implanted hardware is of very low economic cost; the software frameworks are free. In the experimental tests we have shown that it is possible to communicate to the moving guard, intrusion notifications (by e-mail and by instant messaging), and the first video frames in less than 20 s. In addition, we automatically recovered the frames of video lost in the disruptions in a transparent way to the user, we supported vertical handover processes and we could save energy of the smartphone's battery. However, the most important thing was that the high satisfaction of the people who have used the system.
