As the number of clients increases,the server performance will drop too rapidly to satisfy the client real-time rending requirement because the server loads are increasing linearly for the kind of client/server architecture.The method through peer-to-peer(P2P) to address the server bandwidth and performance bottleneck in large scale massive terrain navigation has attracted much effort based on P2P networks.Due to peers' dynamics,how to find the server peers quickly is the key problem on sharing the tiles based on P2P.A searching model,called GFLOODING,was proposed for the system,which was based on the buffer map(BM) info and group peer map(GPM) info,when deciding from which peers to get the tiles.Compared test result in prototype system indicates that the proposed module can satisfy the large scale massive terrain navigation system,and has higher efficiency than traditional module.
