Scheduled Message Delivery in Delay-Tolerant Networks
With the proliferation of mobile communications, new kinds of network architectures are being defined over the existing static one. Delay-Tolerant Networks (DTN) come to fill in a gap in the existing networking technology: they provide support for communication between peers when there is no end-to-end path available between them. Message forwarding in DTNs can be handled in many ways. In this ...

—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
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
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 کاملHeuristic Congestion Control for Message Deletion in Delay Tolerant Network
Delay tolerant network (DTN) challenges on large delay of communication, opportunistic and intermittent connectivity so that data can be transferred over vulnerable network. Most routing protocols in DTN basing on replicating routing work well over infinite buffer assumption but the performance drops when using with finite buffer due to the congestion problem. However, it is still lack of work ...
