Problem DescriptionUnderwater Sensor Networks (UASN) routing issues:
• High Propagation Delay.
• Higher Maintenance Cost.
• Energy Consumption of Nodes.o Clusters.
• Redundant Data Sensing.o Optimal Values
• Higher Bit Error Rate Because of Acoustic Channel.

Related Work• Node Clustering for UASN have been exploited.
• LEACH: CH selected with optimal number and spent more energy for data transmission.
(Data Aggregation)
• LEACH-L : CH is selected on basis of distance to the sink thus minimizing probability of poor candidate selection.

EENC• Energy Efficient Nested Clustering. • Idle/Awake Awareness• Region division in small virtual grids.• CHs are selected on basis of residual energy.• Formation of small groups in close proximity.• EENC has three phases
o Initial Grouping of Nodes (IGN)o Cluster Formation Phase (CFP)o Data Transmission Phase (DTP)

Number of Nodes
Network Lifetime: Last node Dead
Throughput Ratio (TR): No of packets send by any node towards the sink – No of received packets at the sink.

Number of Nodes
Packet Transmission Ratio (PTR): PTR means the number of redundant packets sent to CH via Active Node + to the sink via CH throughout the network lifetime.

Achievements:
1. We reduce energy consumption by nested clustering.
2. We reduce data redundancy while data transmission.

Future work• Optimal switching of the nodes.
• Testing EENC with DDD routing protocol.
• EENC compatibility with AUV Based schemes.
• Optimal no of Cluster Heads.
