Cross-Layer Design For Energy-Efficient In Wireless Underwater Communication: Acoustic Frequency IDentification Case Study

Thanks to the recent developments on communication techniques, micro-technology and on digital electronics, Underwater Wireless Sensor Networks (UWSNs) are being employed in several types of underwater applications such as wireless identification named Acoustic Frequency Identification (AFID)[1][2]. In this research, we are trying to adapt concepts of wireless acoustic identification to the difficult underwater environment with its hard constraints especially absence of high bandwidth communication (no radio).So, there is a critical parameter in UWSN making challenge because it determines how longer sensor nodes and the entire networks would remain functional. However, in these types of Networks, node’s battery presents a limited energy resource and network lifetime is related to the energy consumption by a node. Thus, in this paper we will propose some contributions and cross-layer design to prolong the AFID network lifetime.
