Metrics Based on Proposals (I)• Average Construction or Initialization overhead
– Upward route• A HELLO message is sent periodically. (ex. 64s for non sleep,
6400s for sleepy network)
– Downward route

Metrics Based on Proposals (II)• Average routing overhead
– No other control traffic is required to probe next hop.
• What else…– Source route overhead (only with downward packet)
• Xxxxx B (0 B if the storing mode is implemented)
– Header size• Xxxxxx B
• What mode– We assumed
• Non beacon• 4g, 4e(CSL), 100kbps FSK
– It can also work with • Beacon, 4e (RIT, TSCH etc.)…• No limitation

Metrics Based on Proposals (III)• Recovery/Re-discovery
– BS down– Propagate Path cost = infinity from top to down– A node which can see neighbor network change the parent– Propagate new path cost which belongs to the new network

Metrics Based on Proposals (IV)
• Recovery time– Time to know BS down
• Ex. If it takes 3 hello missing, it results in 3 * hello interval (s)
– Time to propagate infinity cost from top to down• Max hop * hello interval (s)
– Time to propagate new path cost to belong to new network• Max hop * hello interval ~ Max hop * hello interval * 2 (s)• A node can use hello which is found at early timing and it doesn’t
necessarily take hello interval but it may take shorter time. See upward root establishment time (218.66 sec).
It takes 1h ~ 1h30m to recover upward route for the 10000-network.

Metrics Based on Proposals (V)
• Re-discovery time– When BS recovers, path cost propagates from up to down.
• Less than approximately Max hop * hello interval• A node can use hello which is found at early timing and it doesn’t
necessarily take hello interval but it may take shorter time. See upward root establishment time (218.66 sec).
