Item A Mathematical Model for Node Mobility during Water Current and Tsunami in Underwater Sensor Networks(Institute of Electrical and Electronics Engineers Inc., 2020) Tejaskumar, K.; Dharamdas, I.R.; Chandavarkar, B.R.In underwater acoustic sensor networks (UWASNs), the nodes deployed in the seas and oceans are not always stationary but are affected by changes in their environment. The changes may occur naturally or due to man-made interactions. Naturally occurring phenomena like earthquakes, tsunami, and water currents affect the position of the deployed nodes. The movement of nodes has an impact on the routing of packets involved in underwater communication. Thus, the mobility of nodes is an important factor that has to be taken into account when designing networking protocols for UW-ASNs. This paper talks about the motion of the nodes due to water currents and tsunami propagation. Mathematical models depicting the node's movement due to water currents and tsunami are discussed in this paper. The simulation of the node trajectories is done using UnetStack3. © 2020 IEEE.Item Implementation of Ship Motion Mobility Model in UnetStack for Underwater Sensor Networks(Institute of Electrical and Electronics Engineers Inc., 2020) Prajval, M.; Chandavarkar, B.R.Unlike terrestrial networks, deployed sensor nodes in underwater networks can move due to ship movement, water current, etc. This movement of nodes in underwater networks causes a severe effect in the routing of data to the offshore destinations. Hence, nodes movement is one of the essential factors in designing a context-aware routing for underwater networks. This paper proposes a mathematical model to study the node movement in underwater networks due to the ship movements. Additionally, the proposed model is demonstrated through its implementation in UnetStack3. © 2020 IEEE.
