Fig. 1. Traditional network model and fabric model Abstract—This chapter describes an architecture for slicing, virtualizing, and federating wireless sensor network (WSN) resources. The architecture, which we call KanseiGenie, allows users—be they sensing/networking researchers or application developers—to specify and acquire node and network resources as(More)
This paper deals with challenges in federating wireless sensing fabrics. Federations of this sort are currently being developed in next generation global end-to-end experimentation infrastructures, such as GENI, to support rapid prototyping and hi-fidelity validation of protocols and applications. On one hand, federation should support access to diverse(More)
Metrics that aggregate the state of neighboring nodes are frequently used in wireless sensor networks. In this paper, we present two primitives that exploit simultaneous communications in 802.15.4 radios to enable a polling node to calculate with low power the number (or set) of its neighbors where some state predicate of interest holds. In both primitives,(More)
—The energy efficiency of the widely used converge-cast pattern depends substantially on the choice of medium access control (MAC) and routing protocol. In this paper, we formalize the maximization of convergecast energy efficiency with respect to its MAC and routing as a resource constrained optimization problem. We then analytically show that this(More)
