The goal of the PICORADIO project at the Berkeley Wireless Research Center is to design a low power wireless sensor network able to support a variety of distributed applications. This requires to design a protocol stack that rules the communication among nodes and that consists of the application, network, datalink and physical layers. To derive a low-power and cost-effective protocol implementation from an initial set of requirements, it is critical to use a system design methodology that allows to fully explore the design space and tradeoff different implementation solutions.

Our goal is to develop a design methodology, based on successive refinement, that supports specification, validation and synthesis of wireless protocols. The flow we are defining is based on Cadence VCC for functional validation of the algorithms and for architecture exploration as shown in [1], and UML [2] to specify and document each design step. A methodology based on Metropolis [3], an embedded system design framework that emphasizes design reuse by decoupling computation and communication, is also under development.
