Ensuring reliable sensed data in WSN for a reliable sensor cloud

In recent years, Sensor-Cloud (SC) has attracted increasing attention from both the academic and industrial research community. The SC opens new opportunities in different applications domains since it offers a huge amount of storage space that solves the deficit of sensors. To get a reliable SC, the sensed data must be reliable. For that reason, this paper focuses on building a trust-assisted WSN to guarantee the reliability of the captured values stored in the SC. Hence, we proposed a Fault Tolerant Protocol in WSN for Sensor-Cloud (FTSC) to ensure data integrity and system continuity. To show the performance of our protocol, we compared the performance of a network with the FTSC protocol and without deploying it by using simulator NS2. The results show that our protocol realizes reliability and accuracy in detecting faulty nodes.
