Roteamento em Redes de Computadores DSR – Dynamic Source Routing draft-ietf-manet-dsr-10.txt 19 July 2004 DSR: The Dynamic Source Routing Protocol for Multi-Hop Wireless Ad Hoc Networks Carlos Henrique Pereira Augusto

DSR – Dynamic Source Routing – Reativo ( on demand ) – Dois mecanismos: Route Discovery Route Maintenance

DSR – Dynamic Source Routing – Usa roteamento pela fonte explícito – cada pacote carrega o caminho completo ou – Roteamento pela identificação do fluxo
