An Energy Efficient Routing Protocol in Underwater Wireless Sensor Networks

Underwater wireless sensor network (UWSN) is a specific kind of sensor networks that is used for underwater environments exploration especially the oceans by means of acoustic channels. There are some challenges in this kind of networks such as limited bandwidth, high and variable delay, high energy consumption, high error rate of the channel, multipath fading, minimum lifetime and so on. Sensor nodes in this type of networks tackle resource challenges like limited power, memory space and processing pace. Sensors are utilized for military operations, underwater explorations and surveillance. Every sensor in the UWSN consumes more energy in comparison with the terrestrial sensor networks, because they use acoustic technology. Node clustering is the most common way to organize the data traffic and intra-communications reduction along with scalability and energy consumption improvement. Since in this article a routing algorithm based on fuzzy clustering and with balanced energy consumption in the UWSN is proposed. Simulation results show that the proposed algorithm is efficient due to its energy consumption reduction and throughput improvement in comparison to DABC algorithm [1].
