Vehicular Delay-Tolerant Networks
Vehicular Delay-Tolerant Networks (VDTNs) are composed of mobile nodes that communicate wirelessly with each other to forward data despite connectivity issues. This paper focuses on the problem of some nodes trying to impair the communication of a VDTN. In the paper we study the case of nodes that delay the forwarding of messages that is a particularly difficult to detect form of misbehavior. W...
متن کاملVehicular Delay-Tolerant Networks
—There are problems of low delivery radio and high transmission delay in Vehicular Delay-Tolerant Networks (a.b. VDTN. To address these problems, this paper proposes a Vehicular Delay-tolerant Network routing algorithm based on Contention (a.b. VDNC). VDTN algorithm consists of three strategies: the intersection selection strategy based on the Manhattan distance and traffic information, the fi...
متن کاملVehicular Delay Tolerant Networks
Traditional networks suppose the existence of some path between endpoints, small end to end round-trip delay time, and loss ratio. Today, however, new applications, environments and types of devices are challenging these assumptions. In Delay Tolerant Networks (DTNs), an end-to-end path from source to destination may not exist. Nodes may connect and exchange information in an opportunistic way....
متن کاملPhase Transition Behavior of Message Propagation in Delay Tolerant Vehicular Ad Hoc Networks∗
Abstract– The vehicular networking environment is characterized by time-varying traffic density and relatively high vehicular mobility rates. Enabling networking in the vehicular environment is challenging due to the rapidly changing topology and the vast network of roadways. In this article, we present an analytical model to describe the behavior of message propagation in a delay tolerant netw...
متن کاملGeoSpray: A geographic routing protocol for vehicular delay-tolerant networks
Vehicular networks are characterized by a highly dynamic network topology, and disruptive and intermittent connectivity. In such network environments, a complete path from source to destination does not exist on the most part of the time. Vehicular delay-tolerant network (VDTN) architecture was introduced to deal with these connectivity constraints. VDTN assumes asynchronous, bundle-oriented co...
