a wsn platform to support middleware development
According to the application domain, Wireless Sensor Networks (WSNs) differ in a number of ways (e. g., deployment strategy, node mobility, available resources, node heterogeneity, topology, sensor coverage, Quality of Service (QoS), network size, lifetime, connectivity). This diversity is an obstacle to the development of a standard platform (hardware / software) that eases the task of building sensor networks applications. In this paper we present the design principles of a middleware solution that can be adapted to different application scenarios. We also present a mobile sensor and actuator platform that has been developed at the University of Coimbra in order to evaluate the performance of middleware solutions.
