As wireless sensor networks (WSNs) become larger and more widespread, new systems are required to manage them more effectively. Owl Platform is a multi-layered architecture which attempts to provide a simple, efficient infrastructure for managing data generated by WSNs. A proof of concept implementation is provided as a set of network protocols, multi-language libraries, prototype services, and applications supporting research and commercial activities. The motivation, design, and evaluation of this system are explored and compared to past and
current alternatives. Such a system is capable of scaling to tens of thousands of devices, supported by off-the-shelf hardware.
