“…Starting from our early work in [15], where the network selection was performed according to some performance parameters and with a scoring method for different networks, we here propose MOVE, a procedure that continuously measures all available networks quality on the basis of some predefined parameters. It allows a mobile device to autonomously and opportunistically access the network that is able to provide connectivity with a given level of network quality.…”

Next-generation mobile networks (5G) are defined to provide access in the framework of heterogeneous systems where it is crucial to have “always on” and “everywhere connectivity” capabilities. This is of fundamental importance even in 4G mobile systems, down to 3G and also Wi-Fi and WiMAX. In order to guarantee access to users with handheld devices equipped with multiple radio interfaces, an automated and reconfigurable tool for selecting the best network to be connected with is needed. This should be achieved by avoiding service outages. Current vertical handovers, i.e., switching from a network to another, are essentially based on power received levels and often do not avoid temporary service outages. We propose in this paper a procedure to access mobile networks by sensing multiple performance parameters related to networks available in the considered area. We target at maximizing the probability of accessing the wireless medium despite the technology used. We develop an algorithm, based on dynamic programming, able to select the most suitable network. We present the performance of the proposed algorithm both on the basis of computer simulations and on tests performed in an Arduino-based hardware platform

“…Seamless handover [7] extends NEMO [8] by using multiple interfaces of the same technology (LTE) to support high-speed mobility. Dynamic network selection [9] was proposed to switch from a poor performance network to a better one. However, most of the research in this domain has been confined to single interface usage at any given time, while other interfaces work as backups or assistances for fast handover.…”

With the development of modern high-speed vehicles and mobile communication systems, there is a strong demand for operators to provide stable and high-quality onboard Internet services. However, the vehicle-to-ground links may suffer from several problems, such as insufficient bandwidth and long round-trip time. Although multiple wireless networks, such as WiFi, 3G and 4G, may be available along a track, onboard users hardly have good experiences if they can only visit the Internet via one wireless network, which may be subject to coverage gaps and signal attenuation. In this paper, the link qualities of multiple existing 3G and 4G technologies are first measured in a typical high-speed environment. These 3G/4G networks are candidates for vehicle-to-ground communication. Then, a concurrent multipath transmission scheme together with a network adaptive scheduling algorithm is proposed. The scheme is independent of the protocol stack so that it is easy to deploy. It also provides transparent Internet services for users without requiring the participation of the user devices in any multipath signaling. Meanwhile, the scheduling algorithm works at the network layer, instead of the transport layer, to meet the diverse transmission requirements of the connection-oriented and connectionless user applications. The algorithm can effectively aggregate the bandwidth of multiple available wireless links, as well as avoid the reordering of packets based on both the practical tracing databases and active path monitoring. Analysis and experiments show that the proposed algorithm can provide better onboard Internet services with lower cache requirements than the Earliest Delivery Path First (EDPF) and Weighted Round Robin scheduling algorithms, in terms of bandwidth improvement and packet disorder reduction.
