Expiration Timer Control Method for QoS-Aware Packet Chunking

Development of machine-to-machine communication technologies encourages an increasing amount of mobile traffic by smart phones, cellular phones, and various sensors. This traffic consists of small packets in order to minimize the influence of frame dropping in a data link layer. However, it is necessary to reduce the number of packets flowing into the core network to chunk packets, while satisfying the application requirement of users. In this paper, we propose the expiration timer control method for QoS-aware packet chunking. Our proposed scheme achieves a decrease in the number of packets flowing into the core network while satisfying the QoS of users by adjusting the waiting time for packet chunking depending on the condition of the core network. In this paper, we evaluate the proposed scheme by performing simulations and show that our proposed scheme achieves not only a decrease in packet flow into the core network but also the maintenance of QoS requirement for applications.
