MP2P Architecture Building And Optimizing Based On Mobile Agent

In recent years, mobile peer-to-peer (MP2P) as a brand-new topic, has gradually caused the attention of the academic and industrial, and has become one of the hotspots in the field of computer and communication technologies. MP2P is a result of the combination of mobile wireless network and P2P. The research on the MP2P has vital importance to improve the combat capability of the military, as well as to speed up the process of disaster relief and to promot the flow of information. However, building a MP2P system model is the premise and foundation of research on MP2P, so the design method of MP2P structure model and processing strategy of mobile nodes are studied in this paper.Firstly, a basic overview of the current research on the MP2P is given in this paper, and then the predecessor of MP2P——P2P technology is introduced and four P2P models are described. Finally, the MP2P technology is elicited, including related concepts, unique features of a new field and the faced challenges. On this basis, the issue of building MP2P model is proposed.Aimed at the highly dynamic characteristics between the nodes of MP2P network, a MP2P dynamic architecture model construction method based on a mobile agent is promoted. According to the function and status of nodes, this model is divided into bottom layer with ordinary mobile nodes, which is consisted by the mobile wireless communication equipments consisted by the mobile wireless communication equipment, the middle super-node layer and high-level convergence from the backbone network nodes three layers.MP2P dynamic structural model is based on the idea of cell division. With the increasing of nodes, the model is expanded by splitting iteration of the super nodes and mobile agents. So as to getting a dynamic architecture meets the actual network. For the node mobility, this paper proposed a mobility manage method, which combined the mobile agent and the domain registration mechanism, to improve the success rate of relocation after the node movement, and reduce the difficult of the position brought by the volatility of dynamic architecture model, so as to optimize the network architecture.Finally, by simulation analysis and compared with the existing semi-distributed model, the proposed model can well adapt to the dynamic characteristics of MP2P network. The results show that, the model has advantages in better expansibility, higher rate of node relocation, lower network load and system overhead.
