Surveillance and safety is immensely important in general, while explicitly in case of critical applications, such as oil carrying pipelines from wells to refinery and then to the sea ports for further transportation. Surveillance and safety systems with different combinations already has been proposed for critical infrastructures to make them safe and sound. A huge gap is still there to monitor those critical systems in real time and keep them protected from any kind of unwanted approach. Our paper will propose a robust real time surveillance and secure system, for critical oil pipeline infrastructures, with combination of conventional network and wireless sensor network along with microwave network. Our proposed system shows a significant improvement with eleven times more efficient to conventional system by reducing leakage and loss reporting time to control center. Based on simulation tests investigation, proposed system will be more efficient to detect any threats in real time and can report to central control room without any further delay. © IDOSI Publications, 2012.
