Middleware for Wireless Sensor Networks (WSN) act as the interface point between Wireless Sensor Nodes and higher application layers. A middleware can introduce, support and enhance access to the underlying networks in intelligent ways. Abstraction from the lower sensor layers, Information Processing and Service Provisioning for higher applications are the main task of such middleware. In this paper, the authors identify current challenges in the design of smart middleware for wireless sensor networks, explore the current state-of-the-art and provide an initial architecture for middleware based on the examination.
