When opportunity proceeds from autonomy: A tour-based architecture for disconnected mobile sensors
We consider the case of sparse mobile sensors deployed to implement missions in challenging environments. This paper explores a notion of tour networks that is well suited to circ...

Fundamental scaling laws for energy-efficient storage and querying in wireless sensor networks
We use a constrained optimization framework to derive fundamental scaling laws for both unstructured sensor networks (which use blind sequential search for querying) and structure...

Service availability: a new approach to characterize IP backbone topologies
— Traditional SLAs, defined by average delay or packet loss, often camouflage the instantaneous performance perceived by end-users. We define a set of metrics for service avai...
