An Implementation of RTS/CTS Mechanism and CS Algorithm for Maximum Performance of D2D Communication

In this paper, the performance of the Device-to-device (D2D) communication in the unlicensed spectrum has improved by integrating the Compressive Sensing (CS) algorithm and Ready-To-Receive (RTR) control packet along with the RTS/CTS mechanism. Blocking and false blocking problems are introduced among the neighbor nodes due to the implementation of the RTS/CTS mechanism to overcome the hidden node problem which arises for the deployment of the CSMA/CA protocol to mitigate the interference of D2D communication in the unlicensed spectrum. CS can compress the data thus reduce the needed bandwidth to transmit throughout the channel which significantly reduces the transmission time. RTR control packet broadcast to the respective neighbor nodes if the existing communication is completed prior to the expiration of the timer which reduces the blocking and false blocking problems.
