Car-To-Car Communication For Public Safety And Intelligent Transportation

Cars are a part of doing business and everyday life.Nowadays,cars have increased the quantity but the amount of roads cannot be increase in time increasing rate of car that makes many problems such as accidents,traffic jam and trouble finding one is that we lack traffic information Real-time,ad-hoc wireless communication can help to communicate between cars and cars or between cars and stations to exchange information derived from sensors(Sensors)or measuring tools(Instruments),which we can use information from the car to communicate in car or fast response For example,a vehicle in front of it stops unexpectedly or brings information from communication between Car with a street station to help analyze traffic to reduce congestion traffic and traffic on the road more comfortable that can provide traffic or information to other road users involved with using of road vehicles.The main objective for this thesis is study on Design and Simulation by Simulate to compare capabilities routing protocols for ad hoc wireless communication for communications between cars,compare the capabilities of at least three routing protocols by selecting the most appropriate model for communication between cars in each area,study a quantity requirement of station side transmitter per vehicle per an area by using The Network Simulator(NS-2),test and find the variables that affect the requirement of traffic transmitter,simulate the suitable protocol for Vientiane,simulate an efficiency of vehicle communication when using IEEE 802.15.4 with Vientiane area for traffic reports.In the final simulation,we want to study and compare the simulation results between the most commonly used WLAN or Wi-Fi models currently in use with IEEE 802.15.4,which play many roles in the present.In the first part,we simulate using Vientiane Map.As in previous simulations,but replacing MAC and PHY with IEEE 802.15.4,we compared the appropriate protocols for IEEE 802.15.4 in Vientiane.The amount of information that is higher than the GPSR in all values of the number of nodes increases and has a lower delay value.When the network is bigger,we choose AODV for IEEE 802.15.4.Finally,add or install stations along the way to our main target.Which we found when installed.The same IEEE 802.15.4 roadside station with the car increased,resulting in a higher transmission rate.The achievement and the amount of information per unit time increased by more than 8%to 100 cars and 90 nodes along the way(10 nodes per square kilometer),and there was a tendency for fewer delays,success rates and The amount of information added when the pavement station increases,in the case of car density of more than 55 nodes per square kilometer(500 cars).The side-by-side station slightly affected the WLAN simulation.So we conclude that the communication between the cars is not the communication between the cars.With the car the interesting part is the communication and exchange of information between stations or equipment.
