Testing and validation of a multi-sensor distributed surveillance system

The single location surveillance point (SLSP) is a distributed indoor multi-sensor surveillance system. It incorporates an arbitrary amount of sensors that collect data from a single location, which is the surveillance point. Each sensor collects information from its ambit. Once the crude data has been acquired from the sensors and transmitted to logical decision making server (LDMS) by the session server, the LDMS automatically performs logical deductions based on the data received from the sensors. The LDMS transmits the logical deductions to the human security administrator of the security manager server and/or the end-devices of the nomadic guards. Complicated surveillance systems possess rigid requirements regarding testing and validation. The main endeavor in testing and validating the SLSP system comprised of utilizing an adequate testing and validation process accompanied with sufficient tools to test the SLSP system. The testing and validation process is explained and testing is executed by utilizing two tools. The TCR (test case runner) tool was specifically built for the testing purposes of the SLSP system. A proprietary tool, Nethawk´s EAST (environment for automated systems testing) IMS (IP (Internet protocol) multimedia subsystem) simulator, was utilized in testing. The operability of the constructed prototype accompanied with its successful testing and validation indicates that this endeavor is attained. The paper presents the testing and validation procedure, accompanied with the depiction of the testing tools and their utilization. The research is based on the constructive method of the related publications and technologies and the results are derived through testing and validating the implemented SLSP system.
