Distributed estimation of global parameters in delay-tolerant networks

CPSC538a Time-Sensitive Distributed Applications Literature Survey: Delay Tolerant Networks

The existing TCP/IP based Internet relies on the Internet Protocol to provide a basic level of networklayer functionality that abstracts out the heterogeneous link-layer technologies over which the Internet operates. IP provides end-to-end packet switched communication across the network under certain, often unstated, assumptions. These assumptions do not necessarily apply to the class of chall...

Delay tolerant (delto) distributed TAST codes for cooperative wireless networks

In a distributed cooperative communication system, as the distances between different relay nodes and the receiving nodes may be different, so the performances of distributed space time codes at receiving nodes may badly be degraded if timing synchronization is not assured. In this article, extending the work of Damen et al. we introduce the design of distributed threaded algebraic space-time (...

Distributed Sub-gradient Method for Delay Tolerant Networks

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...

Vehicular 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...
