Abstract A fundamental challenge in underwater wireless sensor network (UWSN) is mobility of sensor nodes during the communication held in the network. There is no fixed location of the sensor nodes present under sea level in wireless sensor network. The nodes are mobile which results in improper communication. Although there are various issues in underwater wireless sensor network, some of them have been encountered in this paper. The paper focuses on node mobility in network during the communication among the nodes. An approach has been proposed in this paper so that communication in the network between the nodes can take place even if the node changes its location. The approach is based on the Euclidean distance. The approach is called as an Arc moment and is used to show how nodes placed in the underwater wireless sensor network can communicate with each other based on various assumptions and conditions.

1 Introduction A self-configuring network of small sensing nodes that communicates among themselves using radio signals, senses, and monitor, understand the physical world is called wireless sensor network. Each node existing in the network is known as motes that are used to collect all the temporary data. UWSN is also known as subnet for WSNs which is used to answer all those queries that cannot be addressed from

the surface using remote sensing techniques. Remotely operated vehicles and autonomous underwater vehicles (AUVs) can measure points against the immense backdrop of an evolving ocean environment. Underwater wireless communication networks (UWCNs) are a network that consist of some sensing devices and autonomous vehicles that are known as acoustic underwater vehicles which interact for performing various applications such as monitoring, data collection from underwater, recording of climate, sampling for ocean, prevention from pollution and disaster, etc. [1]. For making these above application viable, there is a need of communicating protocols among underwater devices. This acoustic networking is considered as most enable technology for the application of underwater network that helps to acquire a 100 meter distance, where smaller areas are covered by electromagnetic waves. Acoustic network consists of multiple sensing nodes that are deployed for performing monitoring. Large antennae and high transmission power are required at extra-low frequencies for radio frequency (RF) waves for propagating through conductive salty water [2]. Paper is divided into six sections. First section is of introducti
