In the end, it was integrated into commercial service by the company Camineo ([[http://camineo.com/index.php?lang=en](http://camineo.com/index.php?lang=en)]([http://camineo.com/index.php?lang=en](http://camineo.com/index.php?lang=en))). The project aims to develop a series of LBS for visitors to natural and protected areas. It presents the concept and development of a service for searching for species information in a recreation area. WebPark uses caching in a client-server architecture to reduce the impact of the lack of a continuous connection to the Internet. This connection is made via the mobile data network GPRS (General Packet Radio Service), in which the coverage is intermittent in the considered area [19]. Public visits to parks may threaten the integrity not only of the visitor but also of the natural resources and the quality of the visitor experience. For providing visitor tracking data to the staff of conservation units, in [20], a computer simulation modeling application is presented. The goal is to deal with the visitation to the Arches National Park (Utah, USA) without damage to the environment. A travel simulation model of daily visitor use throughout the Park's road and trail network and at selected attraction sites was developed. Simulations were conducted to estimate a daily social carrying capacity for Delicate Arch, one of its main attractions, and for the Park as a whole. In our project, similar information is generated, but we build a prototype to monitor the movement of visitors. The proposal of [PERSON] et al. (2018) is closely related to our work. It considers the forest environment, proposing a technological approach to fire detection. The proposed forest fire surveillance system is designed for the mountains of South Korea. It consists of a wireless sensor network (WSN), a middleware, and a web application. The sensors measure the temperature, humidity, and detect smoke. The middleware program and the web application analyze the data and information collected, generating a real-time alarm when the fire occurs. Finally, the CenWits (2018) project is extremely relevant for this work because it served as a basis for the elaboration of the system proposed here. Nevertheless, the location application proposed in this project used to provide the visitor monitoring and security service adds new types of messages and fields in its headers to allow for improvements and new features. These adjustments allow a faster service to visitors at risk, better media access control, efficient use of wireless communication technology and the resources of mobile terminals. In the present work, we designed an application for visitor assistance within the rain forest environment. LoRa technology is used to exchange data with multiple hops, using DTN techniques, allowing the collaborative geolocation within the natural environment, using wearable terminals and access points, named communication totems. Our work builds upon the state of the art, investigating the use of Low Power Wide Area Network (LPWAN) technology in the forest and proposing appropriate communication protocols for the monitoring and rescuing of people visiting those natural parks.
