Optimal Node Deployment in Multi-Hop Underwater Acoustics Communication Networks

In this paper, we propose a system that features a communication network leveraging multiple underwater nodes optimally deployed to facilitate effective communication in an underwater ecosystem. The nodes are interconnected through an acoustic carrier over the α−ℱ fading model. The performance of the proposed system is analysed in terms of outage probability and average channel capacity. The effectiveness of the proposed deployment scheme is demonstrated over static equidistant node deployment. Further, the results have been analysed for multiple combinations of underwater acoustic parameters. All the results are extensively verified through the Monte-Carlo simulations. Moreover, the asymptotic results are also provided, which overlap and validate the analytical results in high SNR regimes.
