In this paper, an efficient multicast routing protocol was proposed for device to device (D2D) communication which helps in increasing the transmission power efficiency, quality of service (QoS) and also reduces the blocking probability and latency. In our algorithm, the packet transmission sequence is decided by the users need i.e. data demand. Base station (BS) selects one as the cluster head (CH) among the users in this method based on the power level. Cluster head changes for different transmissions and will be able to access all the users at that particular time. For a particular packet transmission BS decides one of the users who have received more number of requests as transmitter and that transmits packets to all the requested users. Routing is done according to our algorithm and by simulation we have shown that transmission power efficiency increases, blocking probability and latency decreases compared with  and .
