2.1.1. General Overview

Figure 2 shows the multi-layer architecture designed to deploy low-cost sensor networks for automatic license plate detection. The use of a multi-layer approach ensures the scalability of the architecture, as it is possible to carry out modifications in each of the layers without a ffecting the rest. In particular, the architecture is composed of three layers:
