Energy efficiency model based on cross-layer analysis in wireless sensor network
Tiande Guo · Computer Engineering and Applications Journal · 2007
Energy efficiency is the critical factor in wireless sensor networks.In this paper,we analyze the energy consuming in the physical and MAC layers and present an energy efficiency cross-layer model of the wireless sensor networks.Firstly,the radio power consumption is discussed and an energy estimation model is proposed.Secondly,combined with the RTS-CTS-ACK mechanism of MAC,an energy efficiency analysis model for multi-packets one hop transmission is presented.One numerical example illustrates the validation of the model.
