One of the important sensing means is through sound wave which is widely used in many medical, technological and scientific applications. Acoustic Sensor Networks (ASNs) are especially important for communication in underwater and underground, and in situations where radio frequency signal is not suitable or unusable. Additionally multimodal sensor networks incorporating acoustic sensors can augment the sensing scope and enhance the performance and functionalities of wireless of sensor networks. This is particularly important given the fact that sensor networks will be an integral part of the emerging Internet of Things (IoT) environment.
In recent years there has been growing interest in the design and development of acoustic sensing technology and deployment of acoustic sensor networks for smart environment monitoring, surveillance, off-shore exploration, disaster prevention and recovery, smart cities and buildings, and biosecurity applications. However, the current technology faces a number of challenges that need to be resolved for those applications to be cost effective, efficient and practically deployable in large scale in the IoT. The slow propagation speed, low bandwidth and inherent noise in environment require new or re-design of protocols and algorithms from the application layer to the physical layer. Some of the unsolved issues include high packet error rate, inaccurate channel modelling, inability of protocols to handle node mobility and environmental noise, high communication overhead, low reliability and high latency in data delivery, lack of efficient congestion control mechanism, poor localization in underwater/underground, and high energy consumption at low frequencies. The objective of this special issue is to communicate and disseminate recent research and success stories that demonstrate the potentials and challenges of acoustic sensor networks to monitor vast ocean, underwater and underground, and thereby to extend the scope of the IoT beyond the earth surface.
