Characterizing Interference in Vehicle Ad Hoc Network on Freeway Segment Under Various Traffic Flow Conditions

A key issue in inter-vehicular communication is to maximize the throughput of information flow while satisfying quality requirements. This study addresses this important issue in vehicular ad hoc networks (VANETs) by investigating the issue of interference. Previous efforts to solve this problem only consider static network topologies. However, high node mobility and dynamic traffic flow features make the interference problem in VANETs quite different. To address this problem, this work first investigates interference features in VANETs incorporating realistic traffic flow features based on a validated simulation model. Then, analytical expressions are developed to evaluate the interference under different traffic flow conditions. These analytical expressions are validated within the simulation framework. The results show that the analytical characterization performs very well to capture interference in VANETs. The results from this work can facilitate the development of better algorithms for maximizing throughput in the VANETs.
