The revolutionary Fifth Generation (5G) network technology has already been deployed in many countries to provide end-to-end quality-of-service for a wide variety of services, applications, and users with extremely diverse requirements. To accomplish the same, 5G architecture has enabled Multi-Connectivity (MC) in mobile devices, which aggregates various radio resources and enables simultaneous connectivity. Moreover, the current mobile devices are equipped with multiple network interfaces (Wi-Fi/Cellular) as well as dual-stack networks (IPv4/IPv6) support. But, their performance degrades significantly due to variation in network path quality. The current design of the Internet protocol suite has not adapted well to utilize these multiple interfaces for providing better network reliability. Hence, we propose a client only software solution called Path Aware Transport (PAT), which explores communication paths between client and server and adapts to the dynamics of the network to migrate from one Transmission Control Protocol (TCP) connection to another without hampering the user experience. PAT is prototyped and evaluated in 5G using the ns3 simulator. Moreover, it is implemented in the Samsung flagship mobile device with Android Pie. PAT significantly improves the content downloading time up to 20% and the page loading time up to 29% consistently.

The Fifth Generation (5G) network provides a platform for emerging technologies such as vehicular communication, massive Internet of Things (IoT), and tactile internet. It is paving the way to a modern autonomous industry with mobility as a key requirement to achieve seamless end-to-end connectivity. But the current transport layer is not well equipped with the evolving lower layers to deal with the dynamics of the network conditions during mobility. The variation in network conditions and frequent disturbance in lower layers due to handovers causes performance degradation in the transport layer. Hence, we propose a novel solution called ID oriented Socket Layer (IoSL), an end-to-end solution for futuristic applications. It is an ID-based software solution that maintains a unique identifier among the transport layer connections to provide seamless connectivity to the end devices. During user mobility and frequent handover scenarios, it communicates with the lower layers and effectively controls the transport layer for achieving improved Quality-of-Service (QoS) with enhanced user experience. We prototyped IoSL in mobile devices and evaluated the performance using the ns-3 simulator as well as live-air experiments. The experiments are conducted using Wi-Fi and 5G networks, and the results show a significant reduction in reconnection latencies around 33% and improved end-user throughput by up to 16%.
