简介
Vehicular ad hoc network facilitates cooperative awareness applications by periodically sharing basic safety messages (BSMs) with the neighborhood vehicles. As these applications impact human safety, authenticity of BSMs is a key requirement, which however is a challenging task in a dense traffic density where many BSMs are queued up simultaneously for signature verification. As a result, many important BSMs from nearby vehicles may experience significantly long signature verification delays. To overcome this problem, we propose a channel aware signature verification scheme that prioritizes the BSMs from the closer neighbors with the help of a multi-level security queue. The BSM to security queue mapping is done by a k-means clustering based classification algorithm that takes into account the received signal strengths and application dependent safety areas. Simulation results verify the performance …
