What is simulation in wireless sensor networks?
In the creation and enhancement of WSNs, the process of simulation is more essential as it offers a cost-efficient, effective and adaptable approach to assess various network methods, protocols and configurations. Here, we provide the main features and goals of WSN simulation including some of the common simulation tools for WSNs:
Primary Aspects of WSN Simulation:
