    The communication between devices is provided by wireless networks and it is growing rapidly, dependent on the needs. Wireless networks strike the attention of people throughout the world, and the ad hoc network is part of this attention. Ad hoc networks do not need structural mechanisms and are mostly used by the mobile nodes. In ad hoc networks the nodes act as a router and communicate with the other nodes. Ad hoc networks can be used in various places such as campus, shopping centers, buildings and vehicles. Ad hoc network systems without any infrastructure have two kinds of nodes which are mobile and fixed. Actually, node mobility is not taken into account. The aim of this thesis is to find the cheapest way to provide the practical statistical data that will be saved after communication between vehicles depend on road constructing, renewing, development and time schedule of the drivers etc. The data used in the analysis were the route and schedule information of the local city buses. Istanbul Metropolitan Municipality provided the coordinates of the bus stops and time tables for the data collection part. We used MATLAB to edit the data in data analysis part. We used 802.11 standards for the communication of the buses and C++ to create the protocol of data transmission. We wrote Google Earth scripts to observe the data correctness and coded TCL scripts for simulation in NS2 to see and analyze the data transfer between nodes, i.e., the buses. Different ranges of communication are used and analyzed, and their results are shown in this project. To collect more data, thousands of nodes are used, which represent more than 40 bus lines and their paths from different continents including Asia and Europe, which constitute the two sides of Istanbul.
