Strategies for reducing information dissemination overhead in disconnected networks

Abstract

The information dissemination was examined in a special disconnected network architecture where the moving nodes form the network. The nodes have certain kind of limitations, in terms of battery and computing capabilities. We created APF and IOBIO, two protocols for information dissemination in this environment. In this article we present the results of several simulations -run in a simulator created in OMNeT++ -to decide which information dissemination method is optimal for a given mobility environment. The results give us information to further improve the communication in such networks.

Information dissemination algorithms in space deployed ad hoc networks

“…In the last years we have dealt with a special type of ad hoc networks on Earth, where neither central-control nor addressing exists and the information should be disseminated fast, before the period of validity expires and the entire operation depends on the effective spreading of the information as the system has a very special nature [1], [2]. We constructed an information dissemination algorithm named IOBIO (InfOrmation Dissemination Algorithm for BIOlogically Inspired Networks) [3]. In this article, we present its space adapted version (SPIO) which can collect and exchange data on a surface of a distant planet faster than the nowadays used approaches.…”
