Towards Adaptive Multipath Managing: A Lightweight Path Management Mechanism to Aid Multihomed Mobile Computing Devices

Abstract

With the large scale deployment of multihomed mobile computing devices in today’s Internet, the Multipath TCP (MPTCP) is being considered as a preferred data transmission technology in the future Internet due to its promising features of bandwidth aggregation and multipath transmission. However, MPTCP is more likely to be vulnerable to the transmission quality differences of multiple paths, which cause a “hot-potato” out-of-order arrival of packets at the receiver side, and in the absence of a related approach to fix this issue, serious application level performance degradations will occur. In this paper, we proposes MPTCP-LM 3 , a Lightweight path Management Mechanism to aid Multihomed MPTCP based mobile computing devices towards efficient multipath data transmission. The goals of MPTCP-LM 3 are: (i) to offer MPTCP a promising path management mechanism, (ii) to reduce out-of-order data reception and protect against receiver buffer blocking, and (iii) to increase the throughput of mobile computing devices in a multihomed wireless environment. Simulations show that MPTCP-LM 3 outperforms the current MPTCP schemes in terms of performance and quality of service.

A Smart Semipartitioned Real‐Time Scheduling Strategy for Mixed‐Criticality Systems in 6G‐Based Edge Computing

“…Besides, in other complex real-time applications, like parallel industry systems and smart industrial networks [31][32][33], it needs to consider several factors in data transmission and task scheduling; we are also planning to investigate these issues. Moreover, we notice that modern IoT devices are increasingly being equipped with multiple network interfaces; our future work will consider to apply the proposed SSPS algorithm to optimize the promising multipath parallel data transmission methods [34,35] for the multihomed IoT environment.…”

An Adaptive Video Transmission Mechanism over MEC‐Based Content‐Centric Networks

“…There are several protocols in each layer for different communication purposes, for example, TCP and UDP in the transport layer. However, the network layer only runs IP protocol, which unifies the packet forward process and builds the basis for the protocols in higher layers [26,27]. CCN inherits the layered design principle of TCP/IP protocol suit as shown in Figure 1 [7].…”

Multipath TCP-Based IoT Communication Evaluation: From the Perspective of Multipath Management with Machine Learning

“…The standard MPTCP scheduler splits packets in a uniform manner across all available paths. In MPTCP connections, multiple paths will affect each other [15,16]. When the quality difference between the multipath is large, some unnecessary retransmissions will be frequently started and passed through the poor performance path, which may cause data confusion or even buffer blockage, and further seriously reduce the transmission performance [17][18][19].…”
