Design and Simulation of Cooperative Communication Networks for Wireless Sensors in Underwater Environments

The underwater communication environment is complex and changeable, with special requirements for delay and packet loss rate. This paper proposes a cluster-based cooperative sensor network with switchable topology, MAC layer protocol, and routing protocol for underwater environments. Through the dynamic selection of cluster heads and cluster members, and the reasonable setting of the topology structure, the sensors in the network can cooperate in communication and aggregate information to the sink node. The protocol and cluster head nodes are dynamically adjusted according to the network conditions, and the MAC protocol and routing protocol are dynamically switched to ensure that all nodes in the network can successfully cooperate in communication. At the same time, nodes can switch states to ensure the robustness and network life of the entire network.
