Those protocols take time to detect that a node has failed. If a node does not hear a HELLO mesasge that could be due to node failure or lossy link. So a node has to wait long enough. Protocols like CTP rely on datapath estimate and can detect these failures quickly. - om_p _______________________________________________ Tinyos-help mailing list [email protected] https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
