Performance Comparison of Mobility Generator C4R and MOVE using Optimized Link State Routing (OLSR)

Vehicular Ad-hoc Network (VANET) is a specific class of Mobile Ad-hoc Networks (MANET) and asa main backbone for the future technology such as Smart City that facilitate ubiquitous communication. Based on the communication categories, VANETs is divided intovehicle-to-vehicle communication and vehicle-toinfrastructure communication using a wireless network.However, VANET implementation in the real world is still facing difficulty,especially for vehicle-to-vehicle communication. Several research have been done by creatingmobility generator to build a real VANETs environment into a simulation. In this research we studywellknown VANETs’ mobility generators such as C4R and MOVE to see how those generators reflect the performance of Optimized Link State Routing (OLSR) under different scenarios.Real map are used to show how OLSR performedunderdifferent level of vehicle density in the simulation. We measure the performance of OLSR based onpacket delivery ratio (PDR), end to end delay (E2D) and routing overhead (RO)The experimental resultshowsthat VANET scenario produced by MOVE has higher PDR and yield a lower and stable E2D while the value of RO is higher. On the other hand C4R produce a lower PDR, higher E2D and lower RO value.
