Peer-to-peer (P2P) multimedia sharing is widely envisioned as one of the major applications of wireless communication network in the future, and wireless bandwidth constraint is its principal obstacle. Aiming to save bandwidth, a novel P2P lookup protocol named BF-chord is proposed, in which the finger table in chord is changed, shared files' information is compressed into Bloom filters (BFs) before it is broadcasted to P2P system, and the broadcasting nature of wireless channel is exploited as well. Simulation results show that the proposed scheme not only decreases system's wireless bandwidth consumption, speeds object location, but also reduces the index information storage space.
