Abstract
Underwater Wireless Sensor Network (UWSN) is one of the promising technologies having a wide range of applications, which includes underwater natural resources exploration, marine life study and underwater pipeline monitoring. Due to the harsh underwater environment, it is very challenging to provide an energy-efficient mobility-aware routing protocol for data collection. Due to the regular movement of the water currents, it becomes difficult to design a routing protocol that manages mobility of sensor nodes without the need of the localization details and with minimum energy utilization. Another issue of the UWSN is how to efficiently detect and avoid void nodes in a void area. The effect of the void node during routing increases energy utilization of the sensor nodes, which leads to decrease in the network lifetime and packet delivery ratio. In this paper, a Mobility-aware IMU-based Energy Efficient Routing (MIER) protocol for UWSN has been proposed to address issues including i) higher transmission overhead due to flooding of localization information exchange ii) and void node occurrence that leads to higher energy utilization and packet loss. The opportunistic data forward approach has been employed for the node communication. Extensive simulation has been carried out and the results show that MIER outperforms existing related research work in terms of end-to-end delay, packet delivery ratio and network lifetime.

Summary
Underwater acoustic sensor networks have been recommended as an effective technology for the support of aquatic applications ranging from environmental monitoring to intrusion detection [1]. The network topology is highly dependent on water currents Due to this phenomenon, nodes require localization information exchanging. In view of the existing approaches, the latest research works in the underwater networks intend to achieve localization-based routing, since there is no need for path maintenance or exchanging link-state information [4]. I) How to estimate mobility of UWSN nodes considering water current movement with minimum energy utilization. I) A mobility-aware routing protocol that augments neighbor node position estimation with minimum energy utilization in UWSN has been proposed. Ii)To further improve on the network lifetime by minimizing the energy utilization, an opportunistic directional data forwarding algorithm to avoid and prevents the occurrence of void nodes in UWSNs has been explored iii) An estimation strategy for nodes moving to the void area is explored and presented.
