Device to Device (D2D) Communication: Interference Management Perspective

These escalating demands of users have moved telecom operators from old telephony systems to today's technologies of third generation partnership project (3GPP) [i],Long term evolution advance (LTEA) and 5G [ii] but data demands of users are still not pacified because expansion of 5G has provided the need of high connectivity speed with existing mobile networking standards. In such environment researchers found many ways to solve problem like installation of Pico cells which require additional Capital expenditures(CAPEX), operating expenses(OPEX) and base stations. It increases overhead cost. Second method is Green communications. It is a vital technology which implements virtualization, upgrades older system and provide high efficiency. It lies with still one of major disadvantage i.e. system design. Then, researchers go to a new versatile technique i.e. device to device (D2D) communication. On the other hand, increased momentum towards effective design approaches proves that modern age demands are cost effective and need high connectivity traitsas shown in Table I [iii].
