Vehicular Ad-Hoc Networks is an emerging technology and research area since it promises fast and lossless communication among vehicular nodes. Vehicular to Everything communication targets data sharing between vulnerable road users and cars with mobile network assistance soon. Despite the nature of vehicular mobility and density, V2X requires transmitting massive data over a long range and being lossless. LTE is the most promising infrastructure for cellular V2X messaging, but it is still a developing technology requiring more research. To do so, a simulator environment is a fundamental need. In this thesis study, the literature review is conducted to elaborate on the LTE-V2X characteristics and performance evaluations in simulation environments. Moreover, a customized network simulator coupled with a road simulator is built to enable scalable simulation of various traffic scenarios. A set of physical channel configuration parameters is evaluated to maximize the performance of a fast and lossless ad-hoc communication in road traffic. Performance related parameters are listed and explained in the proposed system scheme. Resource selection techniques of C-V2X are reviewed and discussed. Our evaluation and test study illustrates that the resource selection algorithm plays a crucial role according to the calculated packet reception rates. Additionally, besides the prior public simulation studies, which conducted to seek the performance of C-V2X, are utilized to develop an NS-3 based open source C-V2X simulation environment with the geo-based resource selection algorithm implementation as a contribution along with comparative simulation studies. The proposed simulation environment introduces scalable and configurable system level and link level simulations in LTE vehicular networks.
