Abstract: BitTorrent  is  the  most  worldly  adopted  peer  to  peer  file  distribution application protocol that constitutes a huge part of today’s Internet traffic. P2P  model  benefits  BitTorrent’s  peers  in  file  exchanging  process,  by eliminating  a  single  point  of  congestion.  Beside  the  main  P2P implementation  of  BitTorrent  for  file  exchanging,  it  also  has  Client Server communication between peers and tracker. The tracker is used in BitTorrent network for peers’ discovery.  However, tracker does not benefit from P2P characteristics.  Mainly,  it  is  a  single  point  of  failure, also,  scalability  and  load-balancing  are  other traker’s issues. Another problem is that BitTorrent uses eleven overhead messages which help to distribute the file pieces among the peers.  In this research work, we aim to have a pure P2P BitTorrent application, and minimize the messages overhead.  For Discovery, we  propose  a  novel  architecture to decentralize  the  tracker  and  make  it distributed  among  the  peers.  The  proposed  method  reduce  both communication  overhead  and  node  searching  complexities to O(1).  For

Dissemination, we re-implement the existing BitTorrent using Data  Distribution Service  (DDS), which is a Real Time  Publish  Subscribe  (RTPS)  middleware. We  study  the  performance  of  both  the  original and the  proposed  dissemination  protocols.  The results show that the proposed solution can minimize the BitTorrent overhead achieving high goodput, and speed up the file downloading process in most cases.

Refreshment (Tea, cold drink, water and cakes) will be served
