Abstract
The deployment of an IoT network is subject to energy consumption constraints. To minimize service costs, it is essential to optimize the lifetime of objects, which are often powered by unreliable energy sources. This optimization must be based on finely-tuned energy consumption models and those generally proposed in the literature do not take into account all the specificities of the transmission of a connected object. In this article, a refined power consumption model based on in-situ measurements is proposed for an 802.11ah station. This improved model takes into account the number of nodes in the network, the number of retransmission attempts and the various exchanges linked to the higher communication layers. The results show the influence of the number of stations in an 802.11ah network on a station’s energy consumption, and demonstrate that the maximum number is limited by the probability of successful transmission.
期刊介绍：
The IEEE Transactions on Communications is dedicated to publishing high-quality manuscripts that showcase advancements in the state-of-the-art of telecommunications. Our scope encompasses all aspects of telecommunications, including telephone, telegraphy, facsimile, and television, facilitated by electromagnetic propagation methods such as radio, wire, aerial, underground, coaxial, and submarine cables, as well as waveguides, communication satellites, and lasers. We cover telecommunications in various settings, including marine, aeronautical, space, and fixed station services, addressing topics such as repeaters, radio relaying, signal storage, regeneration, error detection and correction, multiplexing, carrier techniques, communication switching systems, data communications, and communication theory. Join us in advancing the field of telecommunications through groundbreaking research and innovation.
