Programming Software-Defined Wireless Networks

Programming wireless networks requires accounting for multiple complex operations, such as monitoring interference and allocating radio resources. Employing the Software-Defined Networking (SDN) paradigm eases the implementation of such tasks when augmented with suitable high-level programming abstractions. In this work, we present a set of programming abstractions modeling three fundamental aspects of a wireless networks, namely state management, resource provisioning, and network state collection. We also describe our proof-of-concept implementation of the proposed abstractions focusing on WiFi networks and show its use for realizing typical control tasks such as mobility management and traffic engineering as Network Apps.
