Questions
- How often do we sync the nodes clocks?
- Memory Structure (how much space on device, how much data for sensor readings, what format to store in)
- Testing Contiki on a device
- Is there a definitive source of contiki help?
Networking questions
- TCP?
- How often to the nodes rediscover the network tree?
- How to discover the network tree (Flood & Prune?)
- Do we keep an entire routing table in memory or just next node?
- Do we trust their neighboUr detection, or write our own?
- They use timers to work out best route, not hop count. This may mean going through many devices. Is it better to wait and broadcast in 1 hop?
- If there is a break in communication do the node still send data onto the closest neighbour or hold onto it?
Decisions
