Routing method with dynamic channel selection in wireless sensor networks is an effective to specify a route, is different from communication between nodes in a common channel, and is able to transmit the data included the attribute information. In this case, a node to be located in the middle of a course uses a different channel, a normal communication between nodes is stayed temporarily and throughput decreases as a result. Instead, for applications to be built by another wireless network originally, it could be expected as an effective communication traffic control method that we are able to avail ourselves to this route, such as emergency information need to send data immediately for example. In this study, we propose a time division communication system that can give right of priority for data transmission involved attribute information by adding element of priority information to transmission data packet. This method has the rule that each router comes up relay node in the middle of priority path temporarily occupies as these nodes of the string, and in contrast, lays other relay nodes not on the course stay all the time, while priority path goes on.
