Simulation Study on ODMRP for Police Ad hoc Networks

Ad hoc network is a type of network built for some specific objectives and not depending on infrastructure. Multicast is important applications for Ad hoc network. ODMRP is a multicast routing protocol for Ad hoc network. It is characterized by simplicity, mesh route, and dynamic topology. However, a detailed simulation study on ODMRP is still missing. Based on OPNET, this article built the model library for ODMRP, including network model, node model, and process model, etc. A group of numerical simulations are done based on these models. Simulation results verify the validity of these models and quantitatively show that the performance of ODMRP decrease with the increase of node movement speed and multicast group size. The model library built by this article can provide ready-to-use services for academic researchers and industrial personnel.
