Radio Frequency Identification (RFID) is gaining significant thrust in many application fields such as identification and real-time localization systems. Consequently, nowadays, the demand for integrated RFID-Sensors networks is increasing. Usually, numerous RFID-Sensors are deployed to form such types of networks. Then, an RFID tag can be located in the reading field of more than one reader that generates duplicated data reception at the base station. The data redundancy transmission causes

... ecessary energy consumption and network overloading that contributes to the augmentation of transmission delays. In this paper, we tackle the data duplication reception problem. We propose an efficient and proactive filtering scheme for redundant data based on a preliminary broadcast. Our scheme allows us to prevent and significantly reduce the redundant data and improve the performances of the integrated RFID-sensor network.
