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). 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.
