FC-WiFi: An OpenFlow Based WiFi Network with Free Configuration

Aiming at the urgent demands on constructing WiFi communication networks under emergency environments such as rescue and relief work, FC-WiFi, a WiFi network based on OpenFlow was proposed. FC-WiFi employs name-based routing algorithm, and has the characteristics as follows: (i) supporting free configuration access for mobile hosts, (ii) sharing information among mobile hosts and servers, (iii) maintaining the ongoing connection during mobile hosts handover between access points. A prototype system is implemented and experiments show that, hosts can communicate with each other when they associate to FC-WiFi with free configuration. The mobile host can keep TCP connections uninterrupted while passing through multiple access points and the handover delay is under the influence of the original configuration.
