Power Consumption Optimization in Underwater Wireless Sensor Networks Based on EECRU Clustering Algorithm for Routing

Underwater wireless sensor networks are a type of sensor networks that are submerged and communicate with each other by sound waves. The fundamental differences between underwater sound propagation and radio waves at ground level, on the one hand, and energy resource constraints, on the other hand, require new criteria for the design of underwater routing protocols. Most routing protocols are based on the location of the sensor nodes. On the other hand, maintaining the position of nodes in underwater sensor networks is the most important issue. In this paper, we propose a position-independent and cluster-based routing protocol in underwater wireless sensor networks called EECRU. The EECRU algorithm uses the concept of special nodes that act as headers. If no header is found, then this algorithm transfers data using the neighbor node method. It also uses the concept of CDMA to obtain information from different nodes and special nodes. The simulation results using MATLAB software confirm that the proposed algorithm is effective in increasing network lifetime and reducing power consumption.
