WCNC - IP-Stream Oriented Management Mechanism in 802.11 Wireless network by Extending SDN
2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017Co-Authors: Hui Yang, Hewu Li, Qian WuAbstract:With the rapid growth of Mobile Internet, supporting different Qos for a variety of mobile applications becomes a great challenge in wireless network more and more. SDN providing huge flexibility on IP stream management in wired networks motivates considerable works on extending SDN to wireless network, but most of them are mainly focused on wireless resource abstraction and management. Different from wired networks, there are lots of complex parameters of wireless resource, which influences the performance of not only one IP stream but also the whole mobile terminal. How to make SDN supporting IP-stream Oriented Management in wireless environment is still far from research. This paper proposes a mechanism of decoupling wireless resource allocation from mobile terminal by mapping different IP flows to different virtual wireless cards, which makes it possible to support integrated management in wired and wireless network. By extending SDN framework to support virtual network interface, the traditional controller has a global view of network and calculates the IP stream policy for the mobile terminal with multiple virtual network interface. Local agent and flow manager are extended on mobile terminal to maintain the state of virtual interfaces and allocate the data-flows to different virtual interfaces. A real SDN testbed is built to evaluate the performance of our mechanism, and the result shows the mechanism achieves efficient IP flow- level management in both wired and wireless network.

GLOBECOM - Reducing Delay in Group Reformation in WiFi Direct networks Through Redundancy
2018 IEEE Global Communications Conference (GLOBECOM), 2018Co-Authors: Utku Demir, Aaron Faulkenberry, Cristiano Tapparello, Wendi HeinzelmanAbstract:The potential benefits of Mobile Ad Hoc networks (MANETs) have led to the development of many protocols in order to control and optimize such networks. However, the automatic creation and evolution of ad hoc networks has yet to be exploited. A novel ad hoc protocol named WiFi Direct has been proposed and standardized by the WiFi Alliance with the objective of facilitating the interconnection of nearby devices. WiFi Direct provides high performance direct communication among devices and includes different energy management mechanisms. However, the current WiFi Direct implementations require user interaction for setting up and maintaining the connection. In this work, we exploit redundancy to enable the automatic and fast reconfiguration of WiFi Direct networks in response to network dynamics. We propose a proactive solution to unforeseen group owner failures in order to minimize the packet loss and network discontinuity time by setting up a redundant group on a second virtual network interface. Through emulation on Mininet-WiFi, we find that the proposed redundant scheme substantially decreases packet loss, providing almost continuous connectivity among nodes, which cannot be guaranteed through traditional WiFi Direct schemes. This is the first detailed work examining the auspicious potential of using an additional network interface to support network reformation using WiFi Direct.
