In this paper, we propose a novel resource management scheme that jointly allocates the transmitpower and computational resources in a centralized radio access network architecture. The networkcomprises a set of computing nodes to which the requested tasks of different users are offloaded. Theoptimization problem minimizes the energy consumption of task offloading while takes the end-to-end latency, i.e., the transmission, execution, and propagation latencies of each task, into account.

Notes on the simulation files:

DTO.m simulates the disjoint task offloading (DTO) method in the manuscript. This file receives the following parameters as its inputs:

1.   Number of single-antenna users, which is equal to the number of tasks

2.   Maximum acceptable latency of tasks

3.   Ratio of RAN latency to the maximum acceptable latency

4.   Computational load of each task

5.   Data size of each task

After receiving the parameters, DTO.m executes the disjoint method and returns the outputs as in the following:

1.      Acceptance Ratio

2.   Radio Transmission latency of all tasks

3.   Propagation latency of all tasks

4.   Execution latency of all tasks

 

JTO.m simulates the joint task offloading (JTO) method in the manuscript. This file receives the following parameters as its inputs:

1.      Number of single-antenna users, which is equal to the number of tasks.

2.   Maximum acceptable latency of tasks

3.   Computational load of each task

4.   Data size of each task.

After receiving the parameters, JTO.m executes the disjoint method and returns the outputs as in the following:

1.      Acceptance Ratio

2.   Radio Transmission latency of all tasks

3.   Propagation latency of all tasks

4.   Execution latency of all tasks.
