Research And Design Of P2P Overlay Network Communication System Based On Ad Hoc

The integration tendency of networks has made Internet a complicated system of heterogeneous access technologies, kinds of function entities and various services. Based on this precondition, It’s an important subject to provide users with various communication services of P2P overlay networks over different heterogeneous networksFirst this paper discusses Mobile Ad Hoc Network (MANET) and P2P network separately, then researches related technologies and Instlink unified communication platform deeply and in system. After realizing that MANET and P2P network have a lot of characteristics in common:self-organized, distributed network, support of dynamic topology, both composed of peers and cooperative works, this paper proposes a novel solution comprised of a MANET (based on DSR), a P2P communication module layering on top of the MANET and a inter-layer middleware mechanism which integrates both of the two, cognize and utilize network topology. In P2P layer I provide an encapsulated data transfer interface to contain varieties of communication services, and then introduce the ideas of cooperative communication and load balance to optimize system design, in order to achieve high-performance with this P2P system.
