| contents | Data collection in an IoT environment requires simple and effective communication solutions to address resource constraints, ensure network efficiency, while achieving scalability. Efficiency is evaluated based on the timeliness of collected data (Age of Information), the energy spent per delivered unit of data, and the effectiveness in utilizing spectrum resources. This paper addresses a random multiple access adaptive system, in which a large number of devices send sporadic messages in non-periodic pattern. In particular, our analysis highlights the potential of Successive Interference Cancellation and identifies an adaptive parameter setting to maximize its benefits as the level of contention on the shared channel varies. An analytical model is defined, easily scalable with the number of nodes and yielding all the relevant metrics. Evidence of the accuracy of the model is given by comparing predicted results against simulations. The model is utilized to assess the trade-off between Age of Information and energy consumption, revealing a sharp relationship between the two. The considered approach lends itself to many generalizations and applications to massive machine-type communications and IoT networks. |
