On The Performance and Modulation Techniques of Underwater Acoustic Sensors Network: Work in Progress

In this paper several computer simulations and pool experiments have been carried out to verify and demonstrate underwater communication between moving acoustic sensor nodes over different distances achieving optimum mutual information. Moreover, a comparison between mobile sensor nodes and multi-hop relay acoustic sensors network is presented. In our comparison we consider all different information theoretic aspects such as: entropy of message signal, information loss, bit error rate, cross correlation, and mutual information in evaluating the communications between sensor nodes. In addition, we estimate a study on the modulation techniques of underwater sensors network. Our work shows that the use of mobile acoustic sensors in underwater communication system is able to provide a reliable wireless link with low probability of error (<0.003) for different sensor velocities. In addition, it is achieved comparable results in terms of the performance based on information theory aspects.
