abstract = {This paper considers decentralized systems of multiple agents that interact in order to perform distributed computing or efficient information transfer in variant, constrained environments. These systems appear in various relevant use cases, including reliable multicast distribution, or dynamic resource allocation in systems in the Internet edge (datacenters, IOT deployments). This paper introduces an abstract, mathematical model, that allows to study analytically the behavior of these systems, as a set of interacting requesters and providers. The paper describes system orbits, and concentrates on the study of single-orbit systems. Ergodicity of system behavior in the single-orbit case is proved, and a full description of the stationary system behavior is derived. Closed expressions of the stationary distribution of requester decisions are provided. Analytical results are validated through extensive simulations. These single-orbit results are a necessary step for the analysis and further optimization of dynamic performance of these systems.},

abstract = {In large low-power networks of battery-driven sen- sors, power outages are a major concern and communication rates have to be carefully designed in order to optimize energy consumption, network connectivity and sensors lifetime. In some IoT use cases, power can be supplied to sensors by way of renewable energy automatic harvesting (solar panels, etc.). Given the high variability of energy arrival processes, energy consumption in sensors, in particular caused by transmissions to the sink, has to be aligned with energy harvesting patterns, so as to maximize throughput while avoiding power outages that may arise when the battery is empty. This paper proposes ODMAC++, an extension to a well-known protocol for sensor transmission scheduling in a WSN. ODMAC++ relies on learning techniques to adapt sensors communication rate to energy harvesting patterns, and uses a beaconing mechanism whose frequency is adjusted based on past measurements on the harvested energy process. Simulations based on analytical energy arrival models and on real solar radiation measurements indicate that ODMAC++ is able to avoid power outages and to cope with battery limitation and energy variations due to variability in time.},

abstract = {LoRa is a long-range, low-power, low-bitrate, wireless telecommunications system, promoted as an infrastructure solution for the Internet of Things: end-devices use LoRa across a single wireless hop to communicate to gateway(s), connected to the Internet and which act as transparent bridges and relay messages between these end-devices and a central network server. This paper provides an overview of LoRa and an in-depth analysis of its functional components. The physical and data link layer performance is evaluated by field tests and simulations. Based on the analysis and evaluations, some possible solutions for performance enhancements are proposed.},
