PAVENET: A Hardware and Software Framework for Wireless Sensor Networks

Wireless sensor networks are attracting attention as a neural system in the coming ubiquitous computing environment. Building a realistic architecture requires a testbed that meets various demands. Therefore, we have designed and implemented a wireless sensor network testbed called PAVENET. PAVENET consists of a hardware module U 3 ,U 3 SDK, which is a development kit for U 3 software, and basenode software, which supports the development of wireless sensor network technology. PAVENET has four characteristic features: hardware level modularization, dual-CPU architecture, hard real-time transaction support, and network layering APIs. These features help us to develop not only application functions, but also wireless communication functions. This paper describes implementation details and a number of implemented applications, such as ANtennary THings, a traffic line detection system, and media access control (MAC) performance evaluation system.
