CodeBlue
- AMDR Routing:
- support for pub/sub
- routing state proportional to the # of publishers (an entry in the table for each publisher)
- route discovery initiated when a device requests to publish data, requires flooding
- a subscriber that wants to receive data from a channel sends a route reply on the reverse path (handles asymmetric links)
- routes are updated through periodic floods (every 15s)
- negative results on mobility
- path metric (PDR)
- for each link, estimate LDR by mapping the measured LQI to a link delivery estimator. This model is determined empirically.
- PDR is the product of all LDRs of the links along the path
- see CodeBlue Technical Report
SMART
Scalable Medical Alert Response Technology (SMART)
Notes:
Good background section.
