Abstract: The present invention relates to a new network architecture and its data transmission method based on percolation. The disclosed network architecture is a server-free and router-free network structure, wherein efficient routing can be operated with percolations based on the six degrees of separation theory in small world network modeling. An information transmission will be divided into two phases: routing phase and data transmission phase. In the routing phase, probe packets will be transmitted and forwarded in the network thus path selections are performed based on small-world strategy. In the second phase, the information will be encoded and transmitted using the paths selected at the first phase. In such a way, an efficient routing and data transmission mechanism can be built which allow us to construct a low-cost, flexible and ubiquitous network.
