A novelty location-based routing scheme and dynamically vary the transmit power in deep sound channel of acoustics

250-258Many papers have examined the current state of underwater sensor networks (UWSN) technologies. The UWSN could be recorded by hydrophones that are suspended in the channel to monitor seismic events on or below the seafloor generated energy that caused by earthquake. In the deep ocean Sound Frequency and Ranging channel, acoustic waves carry the information of seismic events for long range propagation over a few thousands kilometers. In this paper, we present a novel approach of sensor devices as well as routing protocol towards Sound Frequency and Ranging channel for Sound Fixing and Ranging channel technologies. The sound speed increases towards sea surface as water temperature increases. Therefore, we use the oceanography to find a more efficient way of utilizing routing protocol to obtain more effective detection and identification capabilities, and also to dynamically vary the transmit power for underwater sources. We devise a low cost robust routing protocol based on the long-distance transmission Sound Frequency and Ranging channel. The transmission distance can be determined passively by UWSN with minimum control overhead. The routing scheme integrates position and routing functionalities while leveraging different levels to provide high link layer reliability and energy efficient. We developed an algorithm for underwater acoustic power control at different layers of the UWSN signal power which depends on oceanography requirements. Our approach gives a straightforward interpretation of an adaptive location-based routing protocol, which can overcome the location-based UWSN without GPS position. It reduced costs of deployment for the case of long range propagation. The performances are measured according to the number of collisions, energy consumption per bit, and average end-to-end packet latency. The result of simulation is better than other routing protocols such as FBR and static methods
