Embodiment 1

[0048] In a single cellular unit with time division multiple access, 10 users are randomly distributed in the coverage area of ​​the cellular unit and move with different speeds and initial directions. The coverage radius of the cellular unit is 1 km, the uplink channel of the cellular unit uses a transmission bandwidth of 360kHz, and the data transmission rate is 64kbps. The interval δ of each transmission time slot is set to 0.1 second, and the prediction range is 5 seconds in the future, that is, T=50. According to the selected base station hardware equipment model, set the gain of the base station receiving antenna to 18.0dBi, and set the noise figure of the base station receiving end to N F = 2dB, the received signal strength R required by the base station to successfully receive the user's uploaded data packet θ =-100dBm. The base station is equipped with multiple MEC servers for data processing of tasks uploaded by mobile users, and the computing power f that each use...

Abstract

The invention relates to the field of communication, in particular to a resource allocation method for improving the energy consumption efficiency of a mobile edge computing cellular network, which isused for predicting the positions of users in future T time slots and computing the distances between the users and a base station in the future T time slots. The emthod comprises the steps of analyzing and calculating the future communication channel quality of the user and the transmission power required for successfully transmitting the data to the base station based on the predicted distance;and modeling the resource allocation problem into a mixed integer programming problem for solving to obtain an optimal method for allocating the transmission time slot and the transmitting power. According to the method, on the basis of fully utilizing the mobile context of the user, the unloading strategy and the communication resources are jointly optimized, so that the purpose of minimizing energy consumption resources consumed by the user in the system on the premise of meeting the requirement of the user for task processing delay is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a resource allocation method for improving the energy consumption efficiency of mobile edge computing cellular networks. Background technique [0002] With the development of the mobile Internet and smart terminals, a large number of emerging Internet applications have emerged. These emerging applications have brought us a rich and colorful life experience, but at the same time, they have also brought new challenges to communication systems and mobile terminals. A large number of emerging applications are highly sensitive to data processing delay and have high computational complexity, such as face recognition, image analysis, augmented reality, 3D online games, etc. Since mobile terminals are usually powered by batteries and have limited data processing capabilities, it has been difficult to meet the requirements of high computational complexity and low processing delay tolera...
