The invention discloses a connection allocation and scheduling method of a sensor network in the Internet of things, and belongs to the technical field of wireless communication technology and wireless sensor networks. The connection allocation and scheduling method of the sensor network includes the steps that communication with a message receiving server of the Internet of things is achieved to obtain information of the message receiving server of the Internet of things, a proper connection allocation and scheduling algorithm is established according to the obtained information of the message receiving server of the Internet of things, and when a wireless sensor network requests to be connected with the message receiving server, the connection is allocated to the proper message receiving server of the Internet of things according to the established connection allocation and scheduling algorithm. By means of the connection allocation and scheduling method of the sensor network in the Internet of things, good operation of a high-concurrency and large-throughput large project of the Internet of things can be achieved; the optimal connection scheduling algorithm can be selected according to the situation of the message receiving server of the Internet of things, and thus the most reasonable load balance of the message receiving server of the Internet of things is achieved.
