Software-defined networking (SDN) has generated tremendous interest from both academia and industry. SDN aims at simplifying network management while enabling researchers to experiment with network protocols on deployed networks. This article is a distillation of the state of the art of SDN in the context of wireless networks. We present an overview of the(More)
Software Defined Networking (SDN) introduces a logically centralized control plane to run diverse management applications. In practice, a logically centralized control plane is realized using multiple controllers for scalability, reliability, and availability reasons. In fact, for various current and future networks of interest, it is practically infeasible(More)
We present, LOcation based COmmunication (LOCO), a new channel for communication for robots that can act as a fail-safe communication mechanism in contexts of radio failures, given a working localization system. With insights from traditional wireless communication, we formulate a channel model for the location based communication channel where the(More)
We consider the problem of estimating an RFdevice’s location based on observations, such as received signal strength, from a set of transmitters with known locations. We survey the literature on this problem, showing that previous authors have considered implicitly or explicitly various metrics. We present a novel Bayesian framework that unifies these works(More)
