A Cross-Layer Based Intrusion Detection Technique for Wireless Networks

 In  this paper,  we propose  to design  a  cross-layer b ased  intrusion detection  technique for  wireless networks.  In  this  technique  a  combined  weight  value  is  computed  from  the  Received  Signal  Strength  (RSS)  and  Time  Taken  for  RTS-CTS  handshake between sender and receiver (TT). Since i t is not possible for an attacker to assume the RSS exactly for a sender by  a  receiver,  it  is  an  useful  measure  for  intrusion  d etection.  We  propose  that  we  can  develop  a  dynamic  profile  for  the  communicating nodes based on their RSS values throu gh monitoring the RSS values periodically for a specific Mobile Station  (MS)  or  a  Base  Station  (BS)  from  a  server.  Monitori ng  observed  TT  values  at  the  server  provides  a  reliable  passive  detection  mechanism  for  session  hijacking  attacks  since  it  is   an  unspoofable  parameter  related  to  its  measuring  entity.    If  the  weight  value  is  greater  than  a  threshold  value,  then  the  c orresponding  node  is  considered  as  an  attacker.  By  suitably  adjusting  the  threshold  value  and  the  weight  constants,  we  can  re duce  the  false  positive  rate,  significantly.  By  simulation  results,  we  show  that our proposed technique attains low misdetectio n ratio and false positive rate while increasing the packet delivery ratio.
