This paper presents main concepts and issues concerned with the simulation of
Internet of Things (IoT). The heterogeneity of possible scenarios, arising from
the massive deployment of an enormous amount of sensors and devices, imposes
the use of sophisticated modeling and simulation techniques. In fact, the
simulation of IoT introduces several issues from both quantitative and
qualitative aspects. We discuss novel simulation techniques to enhance
scalability and to permit the real-time execution of massively populated IoT
environments (e.g., large-scale smart cities). In particular, we claim that
agent-based, adaptive Parallel and Distributed Simulation (PADS) approaches are
needed, together with multi-level simulation, which provide means to perform
highly detailed simulations, on demand. We present a use case concerned with
the simulation of smart territories.Comment: Proceedings of the IEEE 2016 International Conference on High
