The invention discloses a transmission power and computing resource allocation method based on an Internet of Things task migration period. The method comprises the following steps: S1, determining migration period of migration task of a terminal k; S2, determining energy consumption of the terminal k migration task; S3, constructing a minimization processing model of a terminal computing task migration period according to the migration period and the energy consumption of the terminal k migration task; S4, transmitting power based on the minimization processing model of the terminal computingtask migration period and reasonable allocation with computing resources is carried out. According to the transmission power and computing resource allocation method based on the Internet of Things task migration period, joint pilot frequency, data transmission power and computing resources can be efficiently and reasonably allocated.
