Abstract
The multi-homed mobile devices in the mobile cloud computing (MCC) systems can improve their throughput by allocating the application data over several paths simultaneously, enabled by the promising Multipath TCP (MPTCP) technology. Meanwhile, network attacks against current Internet infrastructures are likely to increase, especially with the widely deployment of MCC systems. When a MPTCP connection is under network attacks and becomes a poor-performing path or a broken path, it can significantly affect other stable paths and in the absence of related schemes to handle this, MPTCP will undoubtedly suffer from serious performance degradation. Moreover, applying MPTCP to cloud data delivery may generally lead to higher energy consumption and is not favorable to a power-constrained mobile device. The proposed MPTCP-La/E2 has been evaluated with a wide range of performance metrics. The simulation results demonstrate how MPTCPLa/E2 outperforms the baseline MPTCP in terms of QoS and energy-savings. In this proposed system applying MPTCP to a MCC mobile device raises a new concern, namely, the high energy consumption for concurrent use of multiple network interfaces. In addition to muting the potentially broken network interfaces for application data delivery and energy saving using QOD Routing protocol model.
