Abstract
As the demand for high-quality multimedia service over wireless networks has increased wireless multicast communication has been researched for many years in efforts to achieve high throughput. Recently, cooperative multicast scheduling scheme was proposed with the goal of achieving high throughput with good fairness. However, although much attention has been directed towards energy efficient communication, energy efficient cooperative multicast design has not received much consideration. Part of the reason for this is that significant relay power consumption is required for user cooperation. In this paper, we model Quality of Service (QoS) of multicast in terms of outage probability when the cooperative multicast scheme is adopted. From the model, we obtain analytical results for QoS and power consumption under a varying number of users and cell coverage of the Base Station (BS). Finally, the analytical models can be used to find the optimal B S's transmission power by predicting system performance if system configurations are given. This can help system deployment and system optimization.
