Deployment Model of an Underwater Sensor Network in a Swimming Pool Environment with a suitable Localization Scheme

Swimming Pool is one of the places where most of the children wish to be. But mostly the swimming pools do not have proper security measures to be done, in case of any emergency. In the world, in totality the reason for death of children is due to drowning while swimming in the pools. To overcome such mortality due to drowning, a new system has been devised to prevent such occurrences using mobile underwater sensors. The system is designed for children who weigh below 10 kilograms. In a specified swimming pool, a number of mobile underwater sensors are deployed. For every child a mobile sensor node is allocated and it is designed to move along with the child. The mobile sensor which is moving along with the child monitors the movement of the child. Researchers have identified the time a normal child can hold its breath is 35 seconds. If a child lies below the water surface for more than 35 seconds, the sensor identifies the child as drowning. So in the starting of the 30 second the sensor passes the message to an alarm and the alarm is activated. The alarm will ring with 100 decibel sound. Here in this real time deployment, PSO algorithm is used to localize the mobile sensor nodes in the swimming pool environment. Thus the proposed work would help saving a child from drowning in a swimming pool. Index Terms — Underwater Sensor Networks, USN Applications, Localization, PSO Algorithm, Acoustic Signals.
