Abstract

Abstract:

Vehicular Ad hoc networks (VANETs) have been attracted attentions to the research area for solving the increasingly serious problem of traffic congestion as well as the improving road safety. Besides vehicles with communication capabilities,VANETs also include infrastructure such as roadside units (RSU) which serves as access points. RSU plays animportant role invehicle-to-infrastructurecommunication. The deployment strategies of RSU are critical and should be carefully studied in VANETs. In order to effectively enhance the network performance, the RSU deployment problem was studied under the realistic vehicular mobility traces. A large scale urban vehicular mobility traces in Beijing has been collected, and the method of interpolation has been used to preprocess the traffic traces collected in Beijing; a new RSU deploymentalgorithm that considering both the centricity and uniformity was proposed to deploy RSU in VANETs to optimize the total performance of the network. Realistic vehicular mobility trace-driven simulation experiments show that the new algorithm caneffectively enhance the network performance.

Key words: vehicular Ad hoc networks, resource allocation, roadside units deployment
