A Connectivity-based Strategy for Roadside Units Placement in Vehicular Ad Hoc Networks

obtained from ECA. The RSUs placement problem is formulated as a combinatorial optimization problem, of which the objective is to maximize the average connectivity probability by searching for an optimal position combination of the given RSUs. Taking part of an actual urban road network as an example, the RSUs placement problem is calculated and the optimal placement scheme is evaluated. Simulation results show that the optimal placement scheme obtained from our strategy leads to the best connectivity compared to uniform placement and hot-spot placement.
