Routing Improvement in Underwater Wireless Sensor Networks for Energy Saving Purposes

Abstract

Underwater wireless sensor networks have attracted much attention in various applications such as natural disasters monitoring, defense, industries, etc. A new routing algorithm for underwater wireless sensor networks is developed and tested. The algorithm shows a better end-to-end delay yet less energy consumption. This was achieved by limiting the data transmission to a number of specific adjacent nodes to whom the transmitter is authorized to send the message. The algorithm performance was compared with other algorithms (depth based routing and cooperative depth based routing protocols) and the results show a better performance.
