Practical green information delivery protocol for sensor-to-vehicle communications

摘要

In this paper, we propose a practical protocol named asynchronous dissemination protocol based on distributed coding (ADDC) as green and reliable information delivery protocol for sensor-to-vehicle communications. In ADDC, packets are shared among sensors and transmitted through Luby-Transform (LT) codes after the transmission of beacon signal and short-period reception to find new packet in the network. Numerical results show that ADDC achieves higher energy efficiency than the conventional cluster-based protocol.
