In our design, normal nodes do not transfer frames and therefore consume less power. However, underwater nodes perform different tasks, resulting in different transmission frequencies. An underwater environment monitoring system includes different functional sensors to measure underwater noises, temperature, salinity and so on. Since different sensors have different properties, the required times for transmission are also different. For example, while detecting the changes of sounds, sound monitoring nodes irregularly report the status of sounds to the network, but underwater temperature and salinity sensor may need to report salinity changes every half an hour. Traditionally, while encountering frames bound for sound sensors or from sound sensors, the temperature and salinity sensors need to receive the frames first. Once finding itself not the destination of the frames, the temperature and salinity sensors abandon the frames, leading to unnecessary power consumption. If energy consumption can be reduced, the temperature and salinity sensors will not require such large capacity power storage so as to reduce the manufacturing cost of building a node and extend the lifetime of underwater nodes.
