Node Mobility Issues in Underwater Wireless Sensor Network

摘要

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.
