Performance evaluation of secure multipath retransmission mechanism in next generation heterogeneous communication systems

摘要: With the standardisation of fifth generation (5G) wireless network interface was established in 3GPP, features 5G arouse great interest both academics and industry, even government. The significant advancements technology will make a increase demand for content-rich streaming media services. What's more, many mobile devices with heterogeneous interfaces (4G, WiFi, 5G) connect multiple paths data delivery simultaneously. Multiple Transmission Control Protocol (MPTCP) is recommended by Internet Engineering Task Force (IETF) to multi-path parallel transmission, which an important transport layer protocol. Although there are attractive benefits using MPTCP delivery, it becomes sensitive attacks. When subflow association suffers from some attacks (e.g. denial service attacks), undoubted that cause large numbers retransmission data. Unfortunately, regular mechanisms retransmit over same path, may receiver buffer blocking. In this study, authors propose effective retransmitting on non-congested path. simulation results show proposed mechanism has better performance than regular’
