Abstract
Sensor networks have long been an active research field. However, deployments are still often specialized for one particular task while emerging commercial products use proprietary low-end technologies. The new CoAP protocol, designed for resource constrained devices and being standardized by the IETF may bring a partial answer to this divergence. However, complexity of needed protocol stacks may limit real deployments. In this paper, we propose a new, open and pragmatic distributed architecture for sensor and actuator networks, based on CoAP, whose goal is to further reduce constraints on devices. By shifting intelligence to a master node and keeping only what is really needed on sensors, it is possible to reduce software complexity on sensors, while keeping a secure, reliable and scalable system providing sensor resources to the global Internet.
