**4. Experiment Analysis**

In this section, we evaluate the performance of the proposed model, PEBN, in OMNets. The OMNets is a free, open source multi-protocol network simulation software, which plays an important role in network simulation.

## *4.1. Parameter Settings*

The article uses the open source simulation tool, OMNets, to make the simulation. The network has a size of 3400 m \* 4500 m and 100–1300 nodes. Each node is moving randomly. Their moving speeds are, respectively, 1 m/s and 10 m/s. After reaching its destination, the node stays there for a random time. The sensing radius of the node is 50 m. The message generation interval is 25 to 35 s, the transmission interval is 17–18 min. The Time to Live is set to 100 min. The matrix update interval is 180 min. In the above simulation environment, we compared the performance of CAOP, SSIS, and SIaOR algorithms and our proposed routing algorithm (PEBN) in the delivery rate, network overhead rate, and hop count with the change of the number of nodes and simulation time.
