چکیده

This paper proposes a modeling of expected link delay (i.e., data delivery delay) on a two-way road segment for carry-and-forward data delivery schemes in vehicular networks. Recently, a lot of vehicles can communicate with each other by dedicated short-range communications (DSRC) for vehicular networking. In the near future, more vehicles will be equipped with DSRC devices because of governmental policies for driving safety. In this paper, we derive a link delay model on a two-way road segment. This link delay model is essential to support multihop infrastructure-to-vehicle or vehicle-to-vehicle data delivery in vehicular networks as disruption tolerant networks. Through simulation, it is shown that our two-way link delay model is more accurate than the legacy two-way link delay model. Furthermore, by applying our model to data unicasting, we show that our model is precise enough to support the efficient data unicasting on vehicular networks. © 2016 Elsevier B.V.

Third-order Decentralized Safe Consensus Protocol for Inter-connected Heterogeneous Vehicular Platoons

In this paper, the stability analysis and control design of heterogeneous traffic flow is considered. It is assumed that the traffic flow consists of infinite number of cooperative non-identical vehicular platoons. Two different networks are investigated in stability analysis of heterogeneous traffic flow: 1) inter-platoon network which deals with the communication topology of lead vehicles and...

Trajectory ⁃ Based Data Forwarding Schemes for Vehicular Networks

This paper explains trajectory⁃based data forwarding schemes for multihop data delivery in vehicular networks where the trajectory is the GPS navigation path for driving in a road network. Nowadays, GPS⁃based navigation is popular with drivers either for efficient driv⁃ ing in unfamiliar road networks or for a better route, even in familiar road networks with heavy traffic. In this paper, we de...

پروتکل مسیریابی خودتطبیقی با محدوده تأخیر برای شبکه های موردی بین خودرویی

Abstract Vehicular Ad Hoc Network (VANET) is a particular type of mobile ad hoc network in which vehicles communicate between themselves using wireless antenna.  Due to unique characteristics of VANETs (e.g. high mobility of nodes and dynamic topology), routing is one of the challenging tasks in such networks. Consequently, delay tolerant networks which consider the disconnect nature of...
