More on Castor: the Scalable Secure Routing Protocol for Ad-hoc Networks

Abstract [en]

Wireless ad hoc networks are inherently vulnerable,as  any  node  can  disrupt  the  communication  of  potentially  anyother  node  in  the  network.  Many  solutions  to  this  problem  havebeen  proposed.  In  this  paper,  we  take  a  fresh  and  comprehen-sive  approach,  simultaneously  addressing  three  aspects:  security,scalability and adaptability to changing network conditions. Ourcommunication  protocol,  Castor,  occupies  a  unique  point  in  thedesign  space: it  does not  use any  control messages  except simplepacket acknowledgements, and each node makes routing decisionslocally  and  independently  of  other  nodes  without  exchangingrouting state with them. This novel design makes Castor resilientto a wide range of attacks and allows it to scale to large networksizes  and  to  remain  efficient  under  high  mobility.  We  compareCastor  against  four  representative  protocols  from  the  literature.Our  protocol  achieves  up  to  two  times  higher  packet  deliveryrates, particularly in large and highly volatile networks, incursno  or  only  limited  additional  overhead  and  it  is  able  to  survivemore severe attacks and recovers from them faster.
