Description
technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a mobile edge computing server joint task offloading, caching and resource allocation method. Background technique [0002] With the rapid development of the Internet and the popularization of 4G / 5G wireless networks, the era of the Internet of Everything has arrived, and the rapid increase in the number of network edge devices has brought massive data at the zettabyte level. Existing data statistics show that most of the data generated by the Internet in the future will be stored, processed, and analyzed at the edge of the network, which poses a serious challenge to the limited computing power and battery power of smart terminals. In response to this problem, existing studies have proposed mobile edge computing offloading technology, by deploying mobile edge computing servers with strong computing capabilities in the network, and offloading user terminal computing t...
