In this paper, we propose a novel architecture for integrated Radio Frequency IDentifiers (RFIDs) and Wireless Sensor Networks (WSNs) to accommodate an array of applications in a cost-effective manner. Integration combines the traceability and sensing capabilities of the two technologies to maximize the effectiveness of the resulting systems. RFID technology extends the ability of WSNs by tracking otherwise unsensible objects. WSNs, on the other hand, provide information on the environment

We propose a novel architecture to integrate these technologies via super nodes that serve as both RFID readers and relay hubs. The count of the super nodes dominates the cost of these integrated networks. Thus, it is crucial to distribute these nodes over the layout in a way that minimizes their count while ensuring coverage. We employ Integer Linear Programming (ILP) to achieve a deployment scheme that addresses such constraints. Our approach generated outstanding results in terms of costefficiency when compared to other WSN/RFID integrated architectures.
