Optimization of rechargeable battery lifespan in wireless networking protocols

Energy optimization is one of the major issues in the telecommunication field and particularly in wireless networks. This optimization is an essential condition for the ubiquity of wireless and mobile networks. Recent studies show that the Information and Communications Technology sector (ICT) (production, distribution, and use) amounts to 1.4% of overall global CO2e emissions. Almost all works on wireless telecommunication protocols focus on a short term vision of energy consumption consisting of the extension of non-rechargeable battery lifespan, the reduction of the consumed energy amount, or the energy use planning. We discuss how a long-term vision of energy consumption can be conducted by taking into account the device's state of health and particularly the rechargeable battery status. We discuss how the improvement of the devices lifespan impacts on the network lifespan and the energy consumption in production and distribution phases and hence significantly improves energy efficiency. . We illustrate the impact of this new paradigm on the routing problem in wireless sensor networks. We compared the new routing approach with well-known methods in terms of nodes and system lifespan. The obtained results show that consideration of the state of health of batteries extends the system life significantly and improves the success rate of data transmission.
