Abstract

In conventional wireless communications systems, ensuring a reliable communication in areas under natural disasters may be physically impossible, because the destruction of the network infrastructure hinders the operation of the transmission protocols usually employed, which are based on the lossless exchange of information. In such scenarios, an emerging concept called links-on-the-fly proves to be very opportune, as it allows for an ad-hoc network architecture with multiple paths being dynamically assembled out of point-to-point lossy links. This way, a message is transmitted from source to destination through various links, many of which may contain errors, and the destination is responsible for collecting these multiple imperfect copies and jointly decoding them to reconstruct the original message. Each link may consist of multiple hops via many relay nodes. The study of this kind of system is incipient in the literature, so that a limited set of network scenarios, channel models, and performance metrics has been analyzed to date. This Research Project aims to reduce this gap, extending the analysis to more general network topologies, more realistic fading models, and a higher number of first-and second-order performance metrics. It is expected that the analytical results may serve as a comprehensive and solid theoretical basis for the adequate dimensioning of practical systems currently under development.
