Water cover large portion of earth, hence it has many resources that need to be explored. So many of researchers work in this field from years. For continuous monitoring of some area sensor network were established. In acoustic environment working of wireless network is tough, hence energy optimization is highly required. This paper has proposed a model AIASNO (Artificial Immune Acoustic Sensor Network Optimization) that works on sensor network communication management for packet routing. For increasing the life span of network nodes were clustered by artificial immune algorithm. Experiment was done in different Acoustic environment. Results were compared with existing models and it was found that proposed AIASNO has improved the packet transfer count and life span of networks as well.
