O acesso à informação é um dado adquirido nas áreas urbanas cobertas por uma infra-estrutura de comunicação robusta. No entanto, a maior parte das áreas do mundo não estão cobertas por tais infra-estruturas. Propomos um sistema de publicação e assinatura de DTN chamado Hikari, que utiliza a mobilidade dos nós para distribuir mensagens sem utilizar uma infraestrutura robusta. A área de Redes Tolerantes a Disrupções/Atrasos (DTN) concentra-se em fornecer conectividade a locais separados por redes com interrupções e atrasos. O sistema Hikari não utiliza identificadores de nó para encaminhamento de mensagens, eliminando assim a complexidade do roteamento associado a muitos esquemas de encaminhamento em DTN. Hikari utiliza informações de caminhos de nós, anunciadas por nós especiais no sistema ou previstas pelo próprio sistema, para otimizar o processo de disseminação de mensagens. Utilizamos o sistema de metrô de Paris, devido à sua complexidade, para validar o Hikari e analisar seu desempenho. Mostramos que Hikari alcança uma taxa de entrega superior enquanto mantém baixas as mensagens redundantes no sistema, o que é ideal ao usar dispositivos com recursos limitados para disseminação de mensagens.

Abstract: Access to information is taken for granted in urban areas covered by a robust communication infrastructure. Nevertheless most of the areas in the world, are not covered by such infrastructures. We propose a DTN publish and subscribe system called Hikari, which uses nodes' mobility in order to distribute messages without using a robust infrastructure. The area of Disruption/Delay Tolerant Networks (DTN) focuses on providing connectivity to locations separated by networks with disruptions and delays. The Hikari system does not use node identifiers for message forwarding thus eliminating the complexity of routing associated with many forwarding schemes in DTN. Hikari uses nodes paths' information, advertised by special nodes in the system or predicted by the system itself, for optimizing the message dissemination process. We have used the Paris subway system, due to it's complexity, to validate Hikari and to analyze it's performance. We have shown that Hikari achieves a superior deliver rate while keeping redundant messages in the system low, which is ideal when using devices with limited resources for message dissemination.
