Distortion Performance of Underwater Acoustic Sensor Networks
International Journal of Distributed Sensor Networks, 2015 The paper studies the distortion performance of multihop underwater acoustic sensor networks. The network is composed of bottom mounted sensor nodes and the sensor to sensor links experience Rician fading. The distortion is evaluated for the case when there is interference from other sensors in the network.
