Relaxation of Distributed Data Aggregation for Underwater Acoustic Sensor Networks

This aspect of the project is concerned with coordinating the sensors in an under water acoustic network in order to collaboratively track an acoustic source. Measurements are taken at each sensor node, and in order to obtain the best accuracy, the measurements should be jointly processed or fused. This requires communication and coordination among the nodes. At the same time, underwater communication is notoriously challenging. Channel conditions change rapidly and high data-rate communications are generally not possible. Consequently, protocols and mechanisms must be used which can adapt to the timevarying and unreliable communication medium.
