A Load-balance and EEDF based strategy for reducing transmission delay of VoIP services in IEEE 802.16e system

To decrease the transmission delay of uplink voice over IP(VoIP)services in IEEE 802.16e sys- tem,a novel strategy which includes a load-balance algorithm and an extended earliest deadline first (EEDF)scheduling algorithm is proposed.Subsequently,this paper analyzes the performance of the pro- posed strategy in terms of transmission delay of VoIP services,system capacity,throughput and compati- bility with IEEE 802 .16e standard.Finally,simulation experiments are carried out to verify the improve- ment of t...
