Abstract

In vehicular ad hoc networks, the basic safety message (BSM) is periodically broadcast by every vehicle on the road. By exchanging BSMs with neighbors, vehicles aggregate the collected information to get aware of driving environment and react promptly in case of any danger. The BSM dissemination is particularly crucial for vehicles at urban road intersections to avoid car collisions. However, blocking from buildings and obstacles at road corners creates a non-line-of-sight (NLOS) condition for vehicle-to-vehicle communications. The direct broadcasting cannot guarantee a reliable BSM delivery. To solve this problem, we consider the relay-assisted scheme and apply the repetitive transmission pattern to increase the successful reception probability. By exploiting the benefit of network coding, we propose two promising network coded relaying schemes, coding at one relay node (RT-NCI) and coding at all relay nodes (RT-NC), to enhance the reliability of BSM dissemination and improve the system scalability. The superiorities of the proposed schemes are verified by simulation results.
