Applying software product line technology to prototyping of real-time object tracking

In this paper, a software product line (SPL) architecture that explicitly captures common features of realtime object tracking systems using Cricket wireless sensors is presented. A software product line process is also presented including user requirements, architecture design, component development, and systems integration. The focus lies on the application of SPL to object location tracking, such as supply chains and transportation. Thus, this paper introduces three prototypes of the SPL member system including shop navigator systems, low/no visibility navigation systems (LVNS), and games for mazes where each one is created from the software product line architecture. The prototypes are experimented with and lessons are learned.
