The invention discloses a pig house monitoring method based on a mobile coordination node and a data temporary storage mechanism. The method comprises following steps of constructing a pig house monitoring system based on the mobile coordination node and the data temporary storage mechanism, wherein the pig house monitoring system mainly comprises three parts of an information collection system, an information management system and a remote monitoring end; and optimizing a wireless sensor network. According to the method provided by the invention, cluster head nodes are selected according to a threshold value T (n) of network nodes; after the cluster head nodes are selected, other nodes select to add in which clusters according to the distances between the other nodes and the cluster head nodes; the cluster head nodes select different transmission modes according to the distances between the cluster head nodes and a coordinate node; and different energy consumption modes are selected according to whether the communication distances of the coordinate node and the cluster head nodes are more than d0. According to the algorithm, the mobile coordinate node is imported; the transmission distances between the cluster head nodes and the coordinate node are optimized; therefore, the energy consumption of the cluster head nodes is reduced; the service life of the network is prolonged; and the good operation of the system is ensured.
