| Sumario: | There has been much technological advancement in the wireless communic ation in the recent past for the intelligent transportation systems among all Dedicated Short - Range Communication or DSRC or Wireless Access for Vehicular Environment (WAVE) has very important role for the autonomous connected vehicles. It is well known fo r its support for the time sensitive safety applications. Along with safety application, the service to provide nonsafety applications is also becoming very popular, these nonsafety applications may include infotainment, electronic toll tax collection and traffic control to name a few. DSRC protocol consists of WAVE Short Messaging Protocol or WSMP which aims to provide real time safety application and it is also able to support some nonsafety related applications. In our dissertation we aim to evaluate the performance of IEEE 802.11p standard for both safety and nonsafety messages. Our sce norio for master thseis consists of fleet of vehicles that are moving with constant speed and in the same direction forming the platoon pattern. The distance between ever y two vehicles is set to be constant and it is kept 200 meters, similarly every vehicle is moving with constant speed of 20 m/sec. To develop the scenorio for Basic Safety Messages, each vehicle is able to generate BSM messages periodically and it fixed pa yload size of 200 bytes and data rate of 6 Mbits/sec. For the nonsafety messages we also compare the perfor m ance of existing protocols such as optimized link state routing OLSR protocol and Ad - hoc O n - demand Routing AODV protocol, the packet size is kept 25 6 bytes at 8 kbps. We have used the metrics such as throughput, packet delivery ratio , packet loss ratio and end to end delay for evaluaing the performance of as optimized link state routing OLSR protocol and Ad - hoc On - demand Routing AODV protocols Our si mulation results conducted in Network Simulator NS - 3 show that WSMP protocol have adequate level of packet delivery ratio and throughput with moderate level of packet loss at lower intervehicle distances and higher packet loss ratio at greater distances be tween the vehicles. On the same way, when the simulation results of as optimized link state routing OLSR protocol and Ad - hoc On - demand Routing AODV protocol are compared it is evident that AODV protocol better performs in terms of throughput, packet deliv ery ratio as well as in terms of packets loss, but AODV protocol being reactive in nature, assumes much higher end to end delay for the packet delivery. |
