Code of Paper: Smart Economic and Mobility Aware Cooperation for Resource Sharing in Multi-Tier Edge Slicing

In this paper, we propose a novel cooperative resource sharing in a multi-tier edge slicing networks which is

robust to imperfect channel state information (CSI) caused by user equipments’ (UEs) mobility. Due to the mobility

of UEs, the dynamic requirements of their tasks, and the limited resources of the network, we propose a smart joint

dynamic pricing and resources sharing (SJDPRS) scenario that can incentivize the infrastructure provider (InP) and

mobile network operators (MNOs). Aiming to maximize the profits of UEs, MNOs and the InP under the task

fulfillment constraints, we formulate an optimization problem by deploying the multi-objective optimization method

where in addition to the resource allocation variables, the price values are also the optimization variables. To solve

the problem, we adopt a new deep reinforcement learning (DRL) method based on a carefully designed reward

function. The simulation results indicate that the proposed resource sharing scenario can increase total profits for

the UEs, MNOs, and InP in comparison to non-cooperative case, while also providing almost complete fairness

among the players. In specific, the obtained results show that the average fulfilled tasks, minimum profit of MNOs,

and average profit for the InP enhanced by 78%, 75%, and 79%, respectively.
