Real-time monitoring of explosives using wireless sensor networks

Abstract

An increase in bomb attacks in present era has boosted the need to have a continuous monitoring of explosives in public places. This paper proposes an effective warning mechanism for security threats in public places such as railway stations so that security corps can take immediate action against bomb threats. Using a multi phase wireless sensor network, the system will provide a technique to reduce, control, and warn about the forthcoming terrorist activity by accurate and fast detection of explosives. Multiple wireless sensor nodes integrated with different types of sensors is used to identify the chemical composition of explosives. Based on different orthogonal techniques, the system collect data from the sensing nodes dynamically aggregate the data and forward to the sink node for further analysis. A mobile node has been introduced to confirm the suspected objects, thus contributing an enhanced target tracking mechanism that reduces number of false alarms.
