Abstract: We introduce a discrete-event simulation model of an AdHoc network considering the presence of clusters and node mobility. The main goal is to study the volume of traffic in relatively large networks of sensor systems and Internet of Things considering fading and network connectivity. We also evaluate relevant parameters such as the mean CPU utilization and the mean queueing time in each node. The model is relatively general in that it combines the traffic from small devices such as sensors as well as more complex intermediate systems such as gateways and Internet nodes. It is also extensible to other types of scenarios and it allows the evaluation of the network under other performance criteria or evaluation metrics. The results show that the model yields simulation values that could be analytically validated by Jackson networks Ver menos
