Demo abstract: WNOS: Software-defined generation of distributed optimal control programs for wireless networks

摘要

We demonstrate Wireless Network Operating System (WNOS), a radically different approach to software-defined networking (SDN) for infrastructure-less wireless networks. Departing from well-understood approaches inspired by OpenFlow, WNOS provides the network designer with an abstraction hiding (i) the lower-level details of the wireless protocol stack and (ii) the distributed nature of the network operations. Based on this abstract representation, the WNOS takes network control programs written on a centralized, high-level view of the network and automatically generates distributed cross-layer control programs based on distributed optimization theory that are executed by each individual node on an abstract representation of the radio hardware. We prototype WNOS on software-defined radio devices and test its effectiveness by considering specific cross-layer control problems. We demonstrate how the global network behavior can be controlled by modifying a few lines of code on a centralized abstraction.
