摘要：During the last decade the Internet of Things (IoT) has taken on great importance in human life flooded by the increased use of new technologies. IoT aims to make users' lives more comfortable. To achieve this objective, the researchers were interested in the communication protocols used which play an important role in the guarantee of quality for the services offered. MAC protocols are in this sense those that have received the most importance. In this context, we are interested in this paper to evaluate the performance in latency and in energy consumption of one of the most used Mac protocols which is the Slotted-Aloha protocol. For this, we propose a mathematical model based on Markov chains which allows to take into account the different aspects of the protocol studied in the IoT environment. The theoretical evaluation of the delay and of the energy consumption are made and a numerical analysis is given for the validation of our model.
