Deploy Mechanism for Virtual-Machine Based Vehicular Ad Hoc Network Simulation

The virtual-machine (VM) based vehicular ad hoc network (VANET) simulation executes VMs as vehicles, on which actual telecom servers and routing protocols are implemented. We would like to create massive VM based VANET simulation to verify that VANET is feasible for emergency communication facility. However, network congestion increased with the number of VMs as the ad hoc network routing protocols created multiple network sessions over a certain part of physical machines. Such network congestion limited scalability.We propose a VM deployment mechanism to reduce network sessions over the physical machines. Our mechanism executes geographically neighboring VMs on the same physical machine. The VMs moves to another physical machine when the simulated vehicles changed positions. Our approach reduced the network sessions by approximately one-sixth. This realize the extensive VM-based VANET simulation.
