Special Issue on Approximate Computing: Challenges, Methodologies, Algorithms, and Architectures for Dependable and Secure Systems

The current trend in energy resources shapes how computing systems will address new challenges the following years. As a matter of fact, trend, by 2040, computers require more than world’s can generate. In very upcoming future, 2025, data centers alone consume 20% all available electricity. A similar already impacts communications side where, for example, consumption mobile broadband networks and terminals is comparable to centers. These trends only accelerate broadening spectrum possible applications Internet Things (IoT), which connect 50 billion devices through wireless connections cloud infrastructure within few
