Energy-Efficient Packet Aggregation Scheme for VoIP Service in Wireless Multi-Hop Network

)간의 트레이드오프 관계를 비용 함수로 표현하였다 .Key Words : VoIP, Wireless Multi-hop Network, Energy, MOS, QoSABSTRACTThis paper proposes packet aggregation scheme for considering energy consumption of mobile devices on guaranteeing quality of voice. To our purpose, we analyze VoIP service on wireless multi-hop channel in terms of delay , packet loss and energy consumption when packet aggregation scheme is applied to VoIP service. Moreover, we induce a cost function with considering of tradeoff relation between quality of voice and energy consumption.
