Throughput and Reliability Analysis of Information Broadcasting Protocol in VANETs

The throughput and reliability indexes of broadcasting protocol is related to contention windows valve and contending nodes in vehicular ad networks. To find suitable contention window value which can optimize the throughput and reliability of broadcasting protocol, this paper propose theoretical analytic model to analysis the relationship between the throughput and the reliability. So, the analysis results show that the proposed analytic model and optimization contention windows value can enhance the system throughput and ensure reliability of information broadcasting.
