MPGE-4 Codec Based Uplink Resource Allocation Scheme for the Video Telephony Service in IEEE 802.16e/m System

摘要

This paper proposes the uplink resource allocation scheme based on MPEG-4 codec for the video telephony service in IEEE 802.16 e systems. The main feature of the proposed scheme is that the base station (BS) exploits a pattern of variablesize frames which is the character of MPEG-4 codec to allocate uplink resources to the mobile station (MS). The simulation result shows the proposed scheme reduces the video telephony service delay and it also increases the efficiency of the radio resource utilization compare to conventional uplink scheduler schemes in IEEE 802.16 e/m system.
