Energy Efficient Routing Scheme for Underwater Wireless Sensor Networks Using Type-2 Takagi-Sugeno-Kang FIS

Routing is essential for data collecting in underwater network applications. In the routing, a set of best forwarding nodes are required for transferring the packets toward the sink. In the case of natural disasters, nodes are stuck and unable to communicate with other nodes which create node disjoint path issues. The existing work has not considered this issue during obstacles such as a natural disaster. This strengthens the energy consumption, packet loss, and degrades the network lifetime. Therefore, we have proposed an interval type 2 takagi-sugeno-kang fuzzy interference system (\({\text{IT}}2 {\text{TSK}} {\text{FIS}}\))-based energy efficient routing scheme for the selection of the best autonomous underwater vehicle \(\left( {{\text{AUV}}} \right)\)-based forwarding nodes. In the proposed scheme, three parameters are used such as depth difference, remaining energy, and link quality as the input of the \({\text{IT2 TSK FIS}}\) rule base system. The node which has high link quality and less depth difference is elected as the best forwarding node. The simulation of the proposed scheme upgrades the performance in terms of the \({\text{PDR}}\), \({\text{EED}}\) and total energy consumption as compared with the existing scheme.
