Some problems exist in current WiFi campus networks, such as limited range of mobile communication, limited host network configuration. Many approaches have been proposed to introduce programmability in wireless networks, and all these systems require special software or hardware in the access point, which raises the issues of practicality. Aiming at single-hop infrastructured network, a solution of software defined mobile communication is proposed for campus WiFi networks, in which mobile hosts can access with free configuration and communicate in high mobility. In this architecture, OpenFlow network is chosen as network infrasture and commercial access points connect to OpenFlow switch directly. The controller is responsible for downloading flowitems containing mobile location, providing mobiles with name-based routing and adjusting reverse path actively for all traffic. A prototype has been implemented and experiments are carried out about mobile communication, in which the performance is measured and analyzed under different configurations. Experimental results show that mobile hosts can achieve mobile communication and the handover delay is not influenced by network configuration for mobile hosts and performance of OpenFlow switch.
