The integration of social networking and Internet of Things (IoT) concepts has attracted a growing interest of researchers and has promised to support new and powerful applications. However, the time it takes from development to the market for SIoT solutions is longer, especially if proper simulations are made to troubleshoot challenges in a timely manner. We propose the use of a multi-thread simulation tool that combines the existing testbeds, such as Network Simulator (Version 2), Devices Profile for Web Services, Objective Modular Network Testbed in Cplus plus, OPTNET, Parallel and Distributed Simulation (PADS), and J-Simtorun simulations in multiple threads to improve performance and save on time when simulating complex SIoT devices that are able to communicate with humans as well as interact with other devices. Through this approach, developers will shorten time-to-market for SIoT solutions and thus afford these solutions to users and improve the quality of life.
