ABSTRACT

Insecurity of human and properties in Nigeria has risen to an alarming situation and calls for immediate attention. Kidnapping has become so rampant that these days not only the wealthy adults are kidnapped but also vulnerable children and the elderly. Technology like the mobile phone which was expected to be a source of development and ease of life has become a supporting tool that these hoodlums use to perpetuate their actions and put the nation in tears all the time. This research investigates the use of Received signal strength (RSS) which is readily available in all mobile devices as a matrix for locating these hoodlums and consequently, the abducted. In this investigation, a model of a wireless network scenario was developed and simulated in MATLAB. The investigation first assumed that radiating element at the base station (localization system) was equipped with a single dipole element and then secondly, a collinear antenna. The user devices were programmed ESP8266 WIFI modules equipped with onboard antenna. RSS data were collected at the base station and analyzed to ascertain if RSS is a practical matrix for Localization system implementation. Both simulation and experimental results has shown the following; that measured RSS decreases with increase in distance and so can be used to develop a range estimation model, influence of the environment is a major impairment to accurate RSS measurement but if the environment is known, the error due to environment can be compensated for in the localization algorithm, more accurate result in RSS-based localization system is possible if decision is based on multiple scans than on a single scan.
