Enhancing Mobility Based on Realistic Models for Vehicular Ad Hoc Networks

Creation and maintaining of the one-to-onecommunication link between the nodes in Vehicular AdhocNetworks are challenging. The model which is very much efficientfor one particular scenario will not work at the same level ofefficiency for another environment. The mobility of the nodes inthe network plays a crucial role in establishing a reliablecommunication model in the VANETs. Analyzing the nature ofmobility inside a particular network based on logical andhistorical data paves an efficient way in the routing of packets bypredicting the best route and improve the quality of the network,reliability, and other performance in terms of serviceability. Thispaper aims to analyze the drawbacks of existing mobility modelsutilizing various network quality parameters by classifying theminto microscopic and macroscopic mobility models. With theinsight gained from the analysis, we propose two methodologieswhere the realistic model for the VANETs can be established. Themodels are architected with the help of the information providedby the Geographic information system. The conventional mobilitymodels include excessive details such as road and street layouts,intersection with traffic signals, acceleration and deceleration,building, and other obstacles in a realistic mobility model, thatrequires prolonged time to design and optimize, it shouldcomplicate the simulation. Designing an effective, realisticmobility model is crucial. The key objectives of this proposal are toarchitect realistic VANETs mobility models by taking into accountthe real-time road environment and actual data according to thetraffic demand and improving the real-time performance ofVANETs
