A NOVEL LAYER BY LAYER ANGLE BASED FLOODING PROTOCOL FOR UNDERWATER WIRELESS SENSOR NETWORKS

This research presents the problem of data routing tn volatile underwater
environment, where providing better communication and maximizing the
communication performance of the network is always a challenging task. Following
are the main issues possess by the environment, radio signals cannot properly
propagate underwater, so there is a need for acoustic technology that can support
better data rates and reliable underwater wireless communications. Secondly, node
mobility, 3-0 spaces and horizontal communication links between the nodes are some
critical challenges to the researcher in designing new routing protocols for UWSNs.
Many algorithms have been proposed to overcome the problem of large propagation
delays and unreliable link quality. Some of them provide better solution for these
issues, yet horizontal communication links between the nodes and unexpected
movements of nodes still need attention.
