Multi-Radio Access Network Assignment Using Dynamic Programming

Abstract

This paper addresses the formulation of an optimisation problem that assigns a user to a multi-network base station for rural broadband access. The base station in this work is a fully off-grid-powered by renewable energy-system with a wireless backhaul link. The solution proposed in this paper relies on a dynamic programming approach, implementing a cost function that balances power consumption and quality of service. The cost is then aggregated using penalties based on the energy harvested and battery charge. The implemented algorithm is demonstrated (in simulations) able to adapt the user assignment to the network load and energy production.
