Wireless sensor networks are gaining more and more attention these days. They gave us the chance of collecting data from noisy environment. So it becomes possible to obtain precise and continuous monitoring of different phenomenons. However wireless Sensor Network (WSN) is affected by many anomalies that occur due to software or hardware problems. So(More)
Nowadays the energy consumption has become a critical challenge in Wireless Sensor Network (WSN). Wireless connection suffer from some weaknesse chiefly fault detection and energy efficiency which stay again the main problems in (WSN). Both was under the scope of research communities and industry engineers. We are interested to the IEEE 802.15.4 standard(More)
Wireless communication presents the most attractive sign of development in this decades. It contributes to the appearance of Wireless Sensor Network (WSN) which is invented in order to increase the supervision capacity for such phenomenon. It gets more regard from both the customers and the research society. (WSNs) is composed from numerous wireless sensor(More)
