In this paper, a three-dimensional (3-D) positioning system using fingerprinting and K-Nearest neighbor is proposed. The implementation of the proposed positioning system based on visible light communication (VLC) is discussed. On-off keying (OOK) modulation, Manchester coding and time division multiplexing (TDM) are utilized to obtain both lossless data and accurate received signal strength indications...
Broadcast is widely used in Vehicle Ad Hoc Networks (VANET) to send emergent messages to the surrounding vehicles. However, with the increase of the broadcast messages, the possibility of conflicts between messages will rise dramatically, leading to a larger delivery latency or loss. A position based broadcast mechanism for inter-vehicle cooperative warning (P-BM) used in VANET is proposed in this...
