The  most  profound  technologies  are  those   that  disappear...  they  weave  themselves   into  the  fabric  of  everyday  life  un>l  they   are  indis>nguishable  from  it                                                                                        (Weiser,  1991)    

IoT  –  Vision   Vision   By  2017  the  Finnish  ICT  industry  is  a  recognized   leader  in  the  IoT  domain  due  to  its  experJse  in   standards,  soXware,  devices,  and  business   models  integraJng  various  verJcal  industry   segments

Technology  challenge  example:   BaQery    life>mes  

•  Universal  deployment  requires  wireless  technology   •  Most  devices  will  rely  on  ba]eries  as  power  sources   •  Longer  ba]ery  lifeJmes  needed  (months,  years,  decades)     •  SoluJon:  Let  the  nodes  sleep  and  save  ba]ery  when  idle!  

Why  sleeping  is  difficult?   •  CommunicaJon  models  rely  on  instant  responses   –  E.g.  Request  –  response,  web  servers  

•  Links  are  kept  up  in  case  a  message  arrives   •  Network  rejoining  is  expensive  (ConnecJon  setup  signaling  in   wireless,  DHCP..)   •  AddiJonal  protocol  exchanges  require  staying  on  for  another  RTT   •  Wireless  communicaJons  and  tail  energy   –  Switching  to  sleep  mode  has  a  high  cost   –  MoJvates  delay  tolerant  and  bursty  operaJon  

Some  solu>ons  For  sleeping   •  Changing  the  communicaJon  model   –  Proxies,  caches,  DTN,  store-­‐and-­‐forward,  publish/subscribe   –  Cross-­‐layer  interacJons   –  Node  accessibility   –  Be]er  synchronizaJon      

•  Improvements  in  L2  to  avoid  staying  on  unless  required   by  the  applicaJon   –  E.g.,  cellular  networks  are  typically  service  agnosJc;  sleep   possible  in  very  small  Jme  scale;  LTE  DRX  works  on  subframe   (1ms)  level   –  Fast  dormancy  in  Release  8   –  CommunicaJon  models  not  taken  into  account  

Example:  Tiny  COAP  sensors   •  Build  a  sleeping  IPv6  based  temperature  sensor   –  Natural  support  for  sleeping  nodes   –  CommunicaJon  models  that  fit  the  problem  at  hand  

•  Is  it  possible?   –  Jari  Arkko  et  al.  at  Ericsson  have  a  demonstrator  

•  Highlights  from  the  implementaJon:   –  –  –  –  –  – 

Consists  of  48  lines  of  assembler  code   HW  capability  to  send/receive  link  layer  frames   Ethernet,  IPv6,  UDP,  COAP,  XML,  and  app MulJcast,  checksums,  msg  and  device  IDs   Approaches  theoreJcal  minimum  power  usage   No  configuraJon  needed  

   

•  IPv6  auto-­‐configuraJon   •  CoAP  POST  to  interest-­‐based  IP  mulJcast  address

Sleeping  cellular  nodes?   •  Can  we  replace  Ethernet  with,  e.g.,  LTE  in  the  previous   example?   •  Power  consumpJon  in  Rel-­‐8  LTE  (currently  being  deployed)   –  Ba]ery  life-­‐Jme  cals)  in  WP6   • 

The  raJonale  of  WP6  is  to  link  IoT   technology  research  and  development     to  innovaJon  and  business.
