Enhancements of Resource Management for Device to Device (D2D) Communication: A Review

For wireless devices; information sharing from one device to another represents the most significant task for typically discovering the right devices and connecting them is extremely critical. In data communication networks, D2D represent a direct connecting path between two nodes. It cannot depend on Base Station (BS). In this type of D2D, communication links are constantly non transparent and it can arise on in-band or out-band of the spectrum. Data communication via Base Station (BS) can reduce data rate and provide proper resource utilization, which includes voice and text service. The direct communication between two nodes may not follow the resource strategy and utilize more power. In this paper, various enhancements of resource allocation scheme used in the Device to Device (D2D) communications are examined. These resource allocation schemes are compared for its merits and de-merits and to identify the areas of improvement for the future resource allocation schemes based on autonomous direct D2D communication.
