Abstract
It is a basic human instinct to explore and understand nature and the development of science and technology. With the advancing science and technology the urge to investigate has further increased (Alias et al., 2009), (Ibrahim et al., 2013). For the effective supervisory control, sensing plays one of the most important roles. To understand the physical world, various sensors such as chemical sensors, gas sensors and electronic sensors have been invented (Chapman et al.,2010). With the advent of wireless sensor networks (WSNs) the field of command, control and communication has experienced a paradigm shift. A WSN is a collection of densely populated low power nodes that are usually deployed for monitoring, surveillance and control applications (R.S et al., 2002). WSNs have found a wide spread application in automatic area monitoring in military, industry, agriculture, health monitoring in remote areas, environmental disaster detection or prevention and the very common automatic movement of escalators.
