A survey on the present state-of-the-art of explosives, detection methods and automatic explosive detection using wireless sensor network

Abstract

Every year there is more and more evidence of an increase in terrorist activity that has spread around the world. In the light of modern technologies and a variety of threats, it is necessary to detect and prevent this with reliable methods. In this regard, the detection of explosives is an active area of research. For this purpose, many detection systems have appeared. Government agencies in various countries are equipped with devices that can detect explosives. However, they are often large in nature, and roads are also publicly visible. Therefore, it is not advisable to use them in the current conditions in public places, such as railway stations, airports, bus stations, and so on. Manual contact is another problem in traditional systems. Therefore, there is an urgent need for the detection of explosives to be integrated into a mobile network, such as the Wireless Sensor Network (BSS). Since the BSS nodes can be hidden from prying eyes, such a network is an ideal method for automatic detection of explosives in real time. The implementation of such networks can pave the way for the installation of BSSs in public places to protect the lives and property of citizens. To this end, we will review the literature on the current state of explosives, their characteristics, and detection methods, including the use of wireless sensor networks (BSS) for automatic detection of explosives in real time. This article provides an insight into the various concepts of explosives and detection methods that can help in further research on creating a defense system for detecting explosives.
