A Multi-Objective Roadside Unit Deployment Model for an Urban Vehicular Ad Hoc Network

Vehicular ad hoc networks (VANETs) are a type of mobile network that forms unified wireless communication between vehicles and roadside nodes. Roadside units (RSUs), as the infrastructure key component VANETs, play critical role in improving performance VANETs. Their deployment can effectively improve network. The goal RSU (RSUD) problem is to install few RSUs possible on both sides roads or intersections so they cover most areas achieve better performance. This paper proposes multi-objective optimization model solve RSUD using characteristics RSUDs urban roads. Our optimized target includes three indicators, which cost RSUs, their coverage area, communications. Since these indicators cannot consensus, this evolutionary algorithm, NSGA-II Pareto optimal solution, problem. simulation results show effectiveness method. Finally, we present an experiment featuring based real traffic environment uses OpenStreetMap; proves our proposed method practical.
