    Abstract
    This research describes explosive trace detection service architecture which combines the strength of the mobile phones, the polymer sensor and next generation cellular network. The aim is to create a system that will assure common men, local population and above all the nation a secured environment, without disturbing their freedom of movement. It would further help the police in detection of explosives more quickly, isolation of suicide bombers, remediation of explosives manufacturing sites, and forensic and criminal investigation. The idea is to use an explosive vapour nanosensor in wireless sensor network or embed it in a mobile phone as a cognitive radio sensor node. The sensor network connects to the mobile network through a gateway while the cognitive radio sensor node into the mobile phone connects to the mobile network by analyzing the Radio Frequency (RF) surroundings and adjusting the spectrum use appropriately. The sensor node senses the presence of the explosives in the surrounding environment of the sensor and then periodically transmits the sensed data to the explosive trace detection application through the Next Generation Mobile Network IP Multimedia Subsystem and middle-ware. The application takes sensed data and explosive vapour characteristics as inputs and using context-aware rules, determines whether certain emergency conditions are met. Then it communicates the location and concentration of the detected explosives to the respective service provider, which in turn would inform the law and enforcement agency, Police and the subscribed users. The viability of this architecture was proved by evaluation of its critical factors: heterogeneity, scalability and adaptivity. This research contributes the knowledge to the general public on the use of mobile phones to provide security services within their immediate environment. Secondly, the explosive trace detection service is a technology use case which provides insights pertinent to the application areas such as the development of the next generation network services, development of mobile phones and development of explosive trace detection equipment. Finally, the government and intelligence agencies will gain knowledge from this research significant to security policy development and law enforcement.
