Περίληψη
In various IoT applications it is essential that the autonomous connected devices have the most up-to-date information, either to be read or posted. In this work, we consider a general setting of a wireless multihop network with multiple data flows and study the interactions of backpressure routing, congestion control, clean energy harvesting and Age-of-Information (AoI). We propose a heuristic scheme that is based on optimal source data rates and routing decisions, enhanced with heuristically determined AoI-based features in the form of a weight scaling method. The feasibility of the solution in terms of satisfying queue stability is proven, and the obtained upper bound on the queue lengths depends on the quotient of the max versus the min weight value. Numerical evaluations point out the improvements of the heuristic scheme in terms of delivering fresh information with priority, as well as the tradeoffs between AoI and optimality.
