Abstract EN
In recent years, P2P file sharing has been widely embraced and becomes the largest application of the Internet traffic.
And the development of automobile industry has promoted a trend of deploying Peer-to-Peer (P2P) networks over vehicle ad hoc networks (VANETs) for mobile content distribution.
Due to the high mobility of nodes, nodes’ limited radio transmission range and sparse distribution, VANETs are divided and links are interrupted intermittently.
At this moment, VANETs may become Vehicle-based Delay Tolerant Network (VDTNs).
Therefore, this work proposes an Optimal Fragmentation-based Multimedia Transmission scheme (OFMT) based on P2P lookup protocol in VDTNs, which can enable multimedia files to be sent to the receiver fast and reliably in wireless mobile P2P networks over VDTNs.
In addition, a method of calculating the most suitable size of the fragment is provided, which is tested and verified in the simulation.
And we also show that OFMT can defend a certain degree of DoS attack and senders can freely join and leave the wireless mobile P2P network.
Simulation results demonstrate that the proposed scheme can significantly improve the performance of the file delivery rate and shorten the file delivery delay compared with the existing schemes.
