Data Dissemination using Multiple RSUs in Vehicular Networks
نویسندگان
چکیده
We propose a dissemination system using multiple roadside units (RSUs) on a two-way roadway. To enhance the performance of data services, data items are disseminated through a hybrid of infrastructure-to-vehicle (I2V) and vehicle-to-vehicle (V2V) communications. Unserved requests in RSU’s coverage are transferred to the next RSU located in a vehicle’s trajectory. In this way, channels are utilized efficiently by not retransmitting the unserved requests, and vehicle can receive the data service with less delays.

Many safety and non-safety related applications have been envisioned in VANETs. However, efficient data dissemination considering the mobility of vehicle is must for the success of these applications. Although the Road Side Unit (RSU) is a stationary unit, both RSU and vehicle have limited transmission range that restricts to shorter connection time. This endures a higher request drop rate spec...

This paper investigates the energy efficiency of Road Side Units (RSUs) by proposing a novel flow and energy management model in Software-Defined Networking (SDN)-based vehicular networks. In the considered scenario, high vehicular mobility and limited coverage area of RSUs cause a degradation in Quality of Experience (QoE) of vehicles and this significantly affects the quality of communication...

We discuss how to efficiently forward data in vehicular networks. Existing solutions do not make full use of trajectory planning of nearby vehicles, or social attributes. The development of onboard navigation system provides drivers some traveling route information. The main novelty of our approach is to envision sharing partial traveling information to the encountered vehicles for better servi...

Vehicular ad hoc networks (VANETs) are the flaming topic of research. VANET comprises of moving vehicles communicating with each other. VANETs involve three types of communication: vehicle to vehicle (V2V), vehicle to roadside (V2R) or vehicle to infrastructure (V2I) communication. VANETs consist of some vital components: RSU, OBU and Trusted Authority. Among them Roadside units (RSUs) are one ...
