Load balancing aware SDMA-based beaconing approach in vehicular ad hocn networks

摘要

Neighborhood discovery is a fundamental link layer service for safetyn and non-safety applications in VANETs. Till now, this service is maden available by beaconing. But, several studies demonstrate itsn inefficiency. In the literature, several papers propose adaptiven strategies to alleviate the channel load problem, but packet loss due ton collision remains an open issue due to the randomness of beacon sendingn through the network. In this paper, we propose an SDMA-based beaconing
