Increasing demands for highly efficient proximity networks led to the derivation of LTE-A (LTE-Advanced) by 3GPP (3rd-Generation-Partnership-Project).Its superior characteristics in terms of capacity and data rates make it a user-friendly option to realize the pipe dream of efficient communication for several communication modules. Device to Device (D2D) communication is one such scheme that adopted the features of LTE-A to ensure the quality of experience and services for the users. D2D aims at establishing device connectivity by interlinking devices in the vicinity. Direct connectivity and connectivity via ENodeB (eNB) are the advisable schemes of D2D Communication. Further enhancement is D2D is realized in the form of side-link which ensures direct connectivity of devices by eliminating eNB routing. This achievement by 3GPP enhances the co-existence of side-link and D2D,which makes it adoptable in various value added services. One such value added service exists as VANETS (Vehicular ad-hoc networks), designed for inter vehicular communication to elevate quality of living of the people by ensuring public safety. This paper mainly focuses on Radio Resource Controller (RRC), Media Access Control (MAC) and ProSe layers of 3GPP protocol stack.
