3 doc.: IEEE 802.15-14-0532-00-0010 Submission 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 September 2014 N. Sato and K. Fukui (OKI)Slide 3 Size of network 121108910000 Avg size of HELLO [B]154.51179.11187.70 Total size for one period [kB]18.258190.481833 Size of network 121108910000 Avg size of RREC [B]23.7929.0345.06 Total number of RREC to esablish all downward route [packets]2084728121275 Total size of RREC to esablish all downward route [kB]4.8132133.515315.8

4 doc.: IEEE 802.15-14-0532-00-0010 Submission 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 September 2014 N. Sato and K. Fukui (OKI)Slide 4

5 doc.: IEEE 802.15-14-0532-00-0010 Submission 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 September 2014 N. Sato and K. Fukui (OKI)Slide 5 Hell o GWGW BS1BS2 BS3BS4 Hell o GWGW BS1 BS2 BS3BS4

6 doc.: IEEE 802.15-14-0532-00-0010 Submission 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. September 2014 N. Sato and K. Fukui (OKI) Slide 6

7 doc.: IEEE 802.15-14-0532-00-0010 Submission 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). September 2014 N. Sato and K. Fukui (OKI)Slide 7 Hell o GWGW BS1 BS2 BS3BS4 Hell o GWGW BS1BS2 BS3BS4
