Abstract

This paper describes a new multicast scheduling scheme for Multi-Massive-Online (MMO) applications in mobile networks. In order to reduce the amount of traffic volume, multicast channels should be fully utilized for information sharing among users while unicast channels are used to notify the current states of the users to the servers. On the other hand, most mobile terminals cannot use both multicast and unicast channels at the same time slot. In such case, each terminal should choose either to receive data in multicast channels delivered from the servers, or to send its state information to the servers while missing the multi casted data In order to provide the optimum tradeoff between sending and receiving the relevant data of MMO, we propose a new scheduling algorithm with which multicast servers enable most mobile terminals to have upload time while they obtain the multicast contents that they prefer. The effectiveness of the proposed algorithm is numerically evaluated.
