PROJECT TITLE :

On Uplink Virtual MIMO with Device Relaying Cooperation Enforcement in 5G Networks - 2018

ABSTRACT:

In this Project, a completely unique protocol is proposed in that mobile terminals (MT) kind a virtual Multiple-input Multiple-output (MIMO) uplink by means that of device relaying on Device to Device (D2D) tier in 5G Cellular Network. The competitive state of affairs is taken into account in that every of the selfish MTs tries to transmit its own data and not relay others' information within the formed virtual MIMO. The main focus is to design an incentive for MTs to create the virtual MIMO and cooperate in relaying others information. A direct revelation on-line mechanism for the BS is meant, so as to assist forming a stable virtual MIMO. A self-punishment mechanism is additionally proposed in that MTs autonomously punish malicious MTs that do not cooperate in relaying. We have a tendency to prove that our designed direct revelation on-line mechanism and proposed self-punishment mechanism enforce all-cooperation (all-C) profile as a Nash equilibrium (NE), under uncertainty in the presence of MTs in the fashioned virtual MIMO. Our simulation results make sure that the proposed protocol, even within the competitive scenario, will increase the bit rate and decreases power consumption at the identical time. The proposed protocol will improve the energy efficiency up to 35 percent compared to a non-cooperative case, i.e., Single-Input Multiple-Output (SIMO) uplink. Moreover, if the multi-user MIMO transmission is employed for the uplink medium access layer, the proposed protocol can improve the energy efficiency up to forty two percent compared to SIMO uplink with multi-user MIMO transmission. Underneath the proposed OCVM protocol with Shapley value fairness, the value of anarchy reaches to 0.78 in the competitive scenario. In addition, the energy potency improvement of our proposed protocol is almost sturdy to the preferences of MTs. Simulation results show that if BS employs our on-line mechanism and MTs autonomously punish malicious MTs, the malicious MTs cannot gain by defecting from relaying alternative MTs' knowledge.
