    Abstract

    The inflexible management and operation of today’s wireless access networks cannot meet the increasingly growing specific requirements, such as high mobility and throughput, service differentiation and high-level programmability. In this paper, we put forward a novel multipath-transmission supported Software-Defined Wireless Network architecture (MP-SDWN), with the aim of achieving seamless handover, throughput enhancement, and flow-level wireless transmission control as well as programmable interfaces. In particular, this research addresses the following issues: (i) for high mobility and throughput, multi-connection virtual access point (MVAP) is proposed to enable multiple transmission paths simultaneously over a set of access points (APs) for users; and (ii) wireless flow transmission rules (WFTR) and programmable interfaces are implemented into mac80211 subsystem to enable service differentiation and flow-level wireless transmission control. Moreover, the efficiency and flexibility of MP-SDWN are demonstrated in the performance evaluations conducted on a 802.11 based testbed, and the experimental results show that compared to regular WiFi, our proposed MP-SDWN architecture achieves seamless handover and multifold throughput improvement, and supports flow-level wireless transmission control for different applications.
