CONET  2013    4th  International  Workshop  on  Networks  of  Cooperating     Objects  for  Smart  Cities  2013  (CONET/UBICITEC  2013)     jointly  held  with   CPSWeek  2013,  Philadelphia,  PA,  USA   April  8,  2013     http://conet2013.deis.unical.it         There  are  three  important  concepts  that  have  gained  relevance  over  the  past   years.  First,  the  concept  of  classic  embedded  systems  where  the  focus  is  on   the  control  of  physical  processes  (machinery,  automobiles,  planes,  etc.).  Se-­‐ cond,   the   notion   of   pervasive   computing   (or   ubiquitous   computing)   that   foresees  everyday  objects  as  having  some  form  of  computation  capacity  and,   in   most   cases,   sensing   and   communication   facilities.   Third,   wireless   sensor   networks   where   small   computing   devices   are   able   to   sense   their   environ-­‐ ment  and  cooperate  in  order  to  achieve  a  common  goal.  We  refer  to  the  uni-­‐ fied  vision  of  these  three  systems  as  networks  of  Cooperating  Objects  (COs).     This   new   vision   is   more   powerful   and   has   a   larger   scope   than   each   of   the   individual  system  concepts  out  of  which  it  evolved.  The  vision  of  Cooperating   Objects  is,  therefore,  quite  new  and  needs  to  be  understood  in  more  detail   and  probably  extended  with  inputs  from  the  relevant  individual  communities   that  compose  it.  Building  on  the  success  of  the  previous  CONET  workshops,   CONET/UBICITEC   2013   aims   at   providing   a   forum   to   discuss   the   similarities,   complementariness  and  advances  of  the  areas  mentioned  above  in  order  to   integrate  them  into  single  coherent  systems.     Topics  of  interest  included:   • Resource  management  of  COs   • Quality-­‐of-­‐Service  in  networks  of  COs   • Hardware  platforms  for  COs   • Mobile  and  distributed  sensing   • Hybrid  cooperation  of  static  and  mobile  nodes   • Communication  and  control  of  mobile  COs   • Distributed  control  and  estimation  over  networks   • Decentralized  algorithms  for  control  over  wireless  sensor  networks   • Decentralized,  distributed,  and  cooperative  optimization   • Applications  of  control  of  COs   • Real-­‐time  aspects  of  COs   • System  software  for  COs   • Communication  support  for  COs   • Real-­‐world  deployments  of  COs   • Applications  of  COs  to  body  area  networks   • COs  in  Complex  Systems   • Security  and  Privacy  in  COs   • Enterprise  Integration  of  COs   • Application  of  wireless  sensor  networks  on  Pervasive  computing   • Closed-­‐loop  applications  of  pervasive  computing   • IoT  Technologies  for  Smart  Cities     The  scientific  contributions  included  five  referred  as  well  as  two  invited  pa-­‐ pers   reported   in   these   proceedings.   Due   to   their   breadth   and   depth   with   respect   to   the   proposed   topics,   the   selected   scientific   articles   allowed   the   analysis  of  the  state  of  the  art  of  techniques  and  methodologies  for  Cooper-­‐ ating  Objects  and  the  development  of  new  wireless  sensor  networks  applica-­‐ tion.   Moreover,   the   main   potential   directions   of   future   research   were   identi-­‐ fied   along   with   the   technologies   that   will   drive   future   innovation   in   the   CO   domain.     The  Organizing  Scientific  Committee  would  like  to  thank  the  invited  speakers,   the   authors   of   the   scientific   contributions,   the   members   of   the   CONET   steer-­‐ ing  and  program  committees,  and  all  people  involved  in  the  organization  of   CONET   2013   whose   precious   contribution   made   possible   to   perform   such   successful  initiative.       The  Organizing  Scientific  Committee   Giancarlo  Fortino,  University  of  Calabria,  Italy
