The invention discloses a source routing method for next single signal channel of power heterolithic point Ad Hoc network, which is a routing method based on a single signal channel. In order to reduce the interference of a high power B node which influences the performance of the network, particularly in the aspect of network throughput, the method introduces a parameter alpha influencing factorsfor each routing, and the parameter is mainly used for expressing the number of B nodes on the path. The number of the B nodes on one routing is bigger, and the influence on the network by the routing to transmit a data packet is greater. Therefore, the routing with smallest influence factors is selected for transmitting the data packet. Compared with various routing protocols based on the singlesignal channel in the prior design, the routing method provided by the invention effectively improves the transmission rate, delaying and loading performances as well as other performances.
