specific Embodiment approach
[0072] Step 1: For the multi-user scenario under multi-base station, build a user task set including task data volume and calculation volume;
[0073] The set of user tasks in step 1 is expressed as:
[0074]
[0075] in, and Indicates that the user n k The amount of data and computation of the task, the subscript n k Indicates the nth user in the kth small base station area, n∈{1,2,...,N} indicates the nth user in the base station area, Represents the set of small base stations, Indicates the set of users within the service range of base station k, K=10, N=100;
[0076] Step 2: Each user in the user task set in step 1 needs to make an uninstallation decision, and set the uninstallation decision variable set
[0077]
[0078] where the unloading decision variable Controls local execution or edge execution of each user task, where, means user n k unloading decision, Indicates that the user offloads the task to the edge server for execution, Indicates th...
