International audience ; The tremendous and rapid development in sensors technology allowed their application in various fields requiring monitoring, such as, transportations, rare species surveillance, agriculture, military activities, medical field, etc. Due to their intrinsic constraints and limitations, several dedicated MAC protocols have been designed for wireless sensor networks and whose main objectives are bandwidth optimization while keeping very low energy consumption. One of the newest proposals is ANT which is emerging as a widely used MAC protocol for wellness and sports sensor devices. In this paper, we give a comprehensive overview of ANT/ANT+ and a comparison between ANT and two established standards: Bluetooth Low Energy (BLE) and 802.15.4/4a. We detail also some practical experiments we conducted to evaluate some characteristics of ANT.

International audience ; A novel multi-technology indoor positioning system, Poucet, designed for military and firefighter operations, is introduced in this paper. A mobile agent, wearing a lightweight tracker, is located in real-time during indoor operations through a combination of outdoor stations and indoor beacons dropped by the agent on his way. Beacons and trackers integrate multiple radio positioning technologies, including Global Positioning System, (Long range Radio (LoRa 868MHz and 2.4 GHz), Ultrawide-band (UWB), and altimeters. Poucet's distributed architecture is presented along with the main features of each of the technologies used. A multi-input fusion algorithm provides continuous and reliable positioning. We report experimental results obtained during benchmarks scenarios conducted by the French National Defense on the presented prototypes.
