Abstract Details

2006, MS, University of Cincinnati, Engineering : Civil Engineering.
Intelligent Transportation Systems, or ITS, is about using technology to solve transportation engineering problems. There is a major push by the Departments of Transportation to use wireless sensors all over the highways to provide accurate traffic information in real-time. Wireless Token Ring Protocol (WTRP), a wireless protocol based loosely on IEEE 802.4 [8] Token Bus Protocol, is an excellent Medium Access Control layer level protocol to prevent data collision in this wireless sensor network on the freeways. The distances between wireless sensors on the freeway were calculated, based on sensor frequency, sensitivity of the receiver and the transmitters, using the Free Space Path Loss Equation. Based on these calculations, it was found that Wireless Token Ring Protocol could fail, as the distances between the sensors was quite large and the data packets got lost, when being transmitted from the last sensor back to the first sensor. The Wireless Token Ring Protocol was modified such that instead of being uni-directional, transmitting data in one direction only; it became bi-directional, transmitting data in both directions. As such, during simulation, it was found that, the performance of the Modified Wireless Token Ring Protocol was better than that of Wireless Token Ring Protocol. The number of data packets that were lost in transmission or corrupted using Modified Wireless Token Ring Protocol was drastically less than that using Wireless Token Ring Protocol, over the same node positions. Hence, the Modified Wireless Token Ring Protocol is more effective than the Wireless Token Ring Protocol to prevent data collision and corruption on the field.
