Abstract:
These Wireless communication systems have been developed to support users’ various requirements. Multicast scheme is proposed for various types of service. Basically, the group Modulation and Coding Scheme (MCS) level for multicast transmission depends on the instantaneous worst channel user to provide reliable communication. However, this causes the low bandwidth efficiency for overall system. In order to overcome this problem, the proposed algorithm considers not only MCS efficiency of groups but also available overall system resources. The performance evaluation shows that proposed algorithm reduce the overall blocking probability and improve the throughput and revenue compared with traditional minimal and Proportional Fair (PF) based schemes.
