Internet of things is a network of objects mainly supported by electronic devices and electronic components such as sensors and electronic cards. These objects can be physical and virtual devices, sensors or actuators, are autonomous and have their own intelligence characteristics. On the other hand, smart environments are those in which sensors and actuators have been integrated, to react to events and to adapt to those present. The environment acquires intelligence through its intelligent components, or through the intelligence resulting from its interaction with other components. Our contribution is a proposal of Cognitive IoT (CIoT) devices structure by adding an agent layer to the device. Such layer provides the device with agent characteristics (intelligence, autonomy, cooperation and organization).

Smart environment needs a lot of sensors in different places. The cost of these sensors is expensive, and to reduce this cost we proposed a mobile robot. This robot carries a range of different sensors that will sense the surrounding environment and send data to the objects in the environment. Since our robot consist of a set of sensors, this can eliminate the possibility of using a huge number of sensor and placing those senssors on all the environment. The process of communication between the robot and the objects in the environment through the MQTT protocol. The IoT Things can control the robot directly through orders received by the robot. RÉSUMÉ. L'environnement intelligent a besoin de beaucoup de capteurs à différents endroits. Le prix de ces capteurs est coûteux et, pour réduire ce coût, nous avons proposé un robot mobile. Ce robot porte une gamme de capteurs différents qui vont détecter l'environnement global et envoyer des données aux objets de l'environnement. Étant donné que notre robot se compose d'un ensemble de capteurs, cela peut éliminer la possibilité d'utiliser un grand nombre de capteurs et de les placer sur tout l'environnement. Le processus de communication entre le robot et les objets de l'environnement se déroule via le protocole MQTT. Les objets de L'IoT peuvent contrôler le robot directement via les commandes reçues par le robot.

With the extensive explosion of web services, the demand for highly reliable
