The embodiment of the invention provides a heterogeneous multimedia sensor network deployment method and device, and belongs to the technical field of wireless sensor networks. The method comprises the following steps: calculating the number of sensor nodes according to the size of a monitoring area and a sensing range of the sensor nodes; using a surrounding distance model to calculate whether a sensor network within the size of the monitoring area and the sensing range satisfies communication property requirements to adjust the number of the sensor nodes; establishing a probability perception model according to the position of a sink node and the positions of the sensor nodes, and calculating the perception probability of each one of the sensor nodes to the sink node; sorting adjacent sensor nodes, and selecting a preset number of sensor nodes in the front to establish a connection with the sink node; sorting links between the adjacent sensor nodes, and deleting a preset number of links at back according to the perception probability. According to the heterogeneous multimedia sensor network deployment method and device provided by the invention, the energy consumption of the nodes can be effectively reduced, and the communication performance of the sensor network can be improved.
