Simulation and Analysis of Protocols in Ad Hoc Network

Simulation and analysis of protocols for network topology is an important research method in network field. The paper introduces the feature and infrastructure of Ad Hoc. The Ad Hoc network and its three protocols (AODV, DSDV, DSR) are presented in detail. The process and method of the simulation of mobile Ad Hoc is analyzed in aspects of objection, scheme design, environment setting and OTel script writing. Finally, the three protocols are simulated by NS2 software, the relevant simulation working diagram and parameter comparison table are presented, and the simulation results are analyzed in aspects of packet delivery fraction and end-to-end time delay. The comparison of simulation results concludes that in the circumstance of non-active movement, the DSR protocol is available due to its low packet loss rate and low end-to-end time delay. While in the circumstance of active movement, AODV protocol is available due to its high packet delivery fraction and low end-to-end time delay, because it embodies the mixed features of DSR and DSDV protocol.
