Titre : Title : An approach for designing and implementing middleware in wireless sensor networks

In this paper, we propose an approach for designing and implementing a middleware for data dissemination in Wireless Sensor Networks (WSNs). The designing aspect considers three perspectives: device, network and application. Each application layer is implemented as an independent Component Object Model (COM) Project which offers portability, security, reusability and domain expertise encapsulation. For result analysis, the percentage of success is used as performance parameter. Such analysis reveals that the middleware enables to greatly increase the percentage of success of the messages disseminated in a WSN. Copyright © 2012 IFSA.
