Abstract:
Roadside units play a vital role in vehicular ad hoc networks. Essential benefits of
roadside units include providing information about traffic jams, accidents, and emergency
messages to drivers in real-time. Because roadside units are expensive, developing a method
to deploy them cost-effectively is pertinent. In this paper, we propose a roadside unit placement
method using a limit number of roadside units to cover the intersections in an urban
vehicular ad hoc network. Our method focuses on identifying potential candidate locations
to place roadside units and minimizing the number of roadside units to deploy. Simulation
results show that the proposed method outperforms existing methods in terms of the number
of roadside units being used and the communication coverage.
