3 pages., 22nd Conference on Innovation in Clouds, Internet and Networks and Workshops (ICIN), via online database., Livestock transhumance in Senegal is done in several areas and more specifically in Sylvo-pastoral areas located in the Ferlo's region where it is difficult or impossible to communicate with terrestrial communication systems. The main reason is due to the existence of white spots. The lack of communication between breeders does not allow the dissemination of vital information such as water points location, bush fires geographic location, epidemic area, and available pastureland. However, in undeserved areas, satellite communications are very expensive for rural population. Therefore, we propose a low-cost communication based on LoRa transmission that enables different services like short message text, voice messages, status of a water points, geographic location. The deployed architecture is a delay tolerant ad-hoc network that can cover a large area with a mesh system.
