碩士 === 國立中正大學 === 資訊工程所 === 94 === The dynamic nature of MANET causes many new challenges in designing robust and scalable P2P system. Although flooding-based techniques are shown to be robust in highly dynamic network, it leads to poor efficiency in terms of bandwidth usage and scalability problem. In this thesis, we propose an adaptive learning and scalable P2P file sharing system based on Swarm Intelligence for MANET, termed P2PSI, which applies the behavior of the real ant colonies to cope with mobility without flooding. Moreover, we also propose cross-layer architecture to optimize P2PSI, reducing the redundant message overhead and query latency. We have experimentally showed superiority of our cross-layer design P2PSI over traditional layered design P2PSI. Additionally, we also compare cross-layer design P2PSI with cross-layer design service discovery protocols, CLdsr and CLdsdv. The simulation results show that our cross-layer design P2PSI can achieve good performance in dynamic topology of MANET.
