Reliability Study of Sensor Node Monitoring Unattended Environment

The sensor node facilitates lot of automation applications including disaster monitoring and surveillance purposes. The sensor nodes placed in a remote environment sends their signal to a sink for further processing and understanding. The sensor network deployed in an anti-third environment on failure provides distrusted data or failure of communication resulting in catastrophic conditions. This paper focuses on studying the reliability of the tandem system. A group of 40 sensor nodes are tested in real time to study the fault characteristics. The study proposes the feasibility and successful working duration of the sensor monitoring applications. The paper provides overall reliability of the sensor monitoring unattended environments. It also emphasize on practical analysis and replacement time for a sensor node monitoring anxious situations.
