Cross-Layer Architecture Applied to Geospatial Information Communication in Embedded Systems

This paper presents a high-level design for cross-layer architecture, it was implemented using an embedded system, which aims an effective communication for Geospatial Information through Wi-Fi technology, in order to emulate an Automatic Dependent Surveillance Broadcasting (ADS-B) system. This system shares geospatial information gathered from one or more Global Navigation Satellite System (GNSS) through another communication mechanism onboard. Since one module of ADS-B was proposed to be necessary for the future for most of the controlled airspace. Therefore, the proposed system presents the main advantage of providing a low-cost solution in low-performance hardware. Also, it brings the capability of increment situational awareness through a graphic interface. In this study a real-world deployment was simulated in order to know the viability for development and node’s location accuracy; results showed that ADS-B functionalities were attained successfully by proposed implementation in mobile devices and it turned into a location aid that could be useful in several scenarios.
