Abstract
The term "Dense networks" is usually used to identify networks having large number of nodes within a small area while affecting network performance. Starting from this concept, different networking solutions were proposed. However, it seems to us that this view is very abstract and needs to be further investigated. Knowing the network density level can be of great importance in determining the network parameters. In this paper, we firstly examine the effect of network size over its performance, then introduce a metric to determine if a network is considered as a "dense network" or not. Finally, we applied our metric on experimental results published in the CRAWDAD dataset site to verify our metric.

Abstract
The use of simulation in training and education enables to prepare personal in realistic environment. But the cost and the complexity to create and reuse simulations often limits their application. In this paper we investigate a low cost and high fidelity PC-based simulator based on Data Distribution Service (DDS) middleware. The main parts of the systems and the architecture, including the hardware and the software are introduced. Real-time networking between distributed simulators is achieved using a reliable distributed communication, which employs publish-subscribe middleware build using OMG-DDS. Result shows these methods could produce low cost, extensible, reliable and distributed simulators.
