AMCTD: Adaptive Mobility of Courier Nodes in Threshold-Optimized DBR Protocol for Underwater Wireless Sensor Networks

Abstract

In dense underwater sensor networks (UWSN), the major confronts are high error probability, incessant variation in topology of sensor nodes, and much energy consumption for data transmission. However, there are some remarkable applications of UWSN such as management of seabed and oil reservoirs, exploration of deep sea situation and prevention of aqueous disasters. In order to accomplish these applications, ignorance of the limitations of acoustic communications such as high delay and low bandwidth is not feasible. In this paper, we propose Adaptive mobility of Courier nodes in Threshold-optimized Depth-based routing (AMCTD), exploring the proficient amendments in depth threshold and implementing the optimal weight function to achieve longer network lifetime. We segregate our scheme in 3 major phases of weight updating, depth threshold variation and adaptive mobility of courier nodes. During data forwarding, we provide the framework for alterations in threshold to cope with the sparse condition of network. We ultimately perform detailed simulations to scrutinize the performance of our proposed scheme and its comparison with other two notable routing protocols in term of network lifetime and other essential parameters. The simulations results verify that our scheme performs better than the other techniques and near to optimal in the field of UWSN.

Dynamic Routing Nodes For Underwater Wireless Sensor Network

“…The main advantage is that there will be less possibility that the data getting lost and the surface sink also have the storage of the data's received. The network attains the stability position only if every node on the network participates and contributes effectively for the data to reach the surface sink (Hai Yan, et al, 2010;Jafri, M.R., et al, 2013;Javaid, N., et al, 2013; Jian-feng yan, yuan-liu liu, 2011).…”

A Routing Protocol Based on Received Signal Strength for Underwater Wireless Sensor Networks (UWSNs)

“…L represents the distance from the receiver to the sink node (node S); and l denotes the RSS vector. The suppressing factor ϕ can be calculated as in Equation (19). Here, h is the distance from the receiving node B to RSS vector.…”

“…In [18], Du et al proposed LB-AGR, which defines an integrated forwarding factor for each candidate node based on available energy, density, location, and level-difference between neighbor nodes, and is used to determine the best next-hop among multiple qualified candidates. The adaptive mobile of courier nodes in threshold-optimized DBR protocol (AMCTD) was proposed in [19]. AMCTD uses adaptive depth threshold, which solves different depth thresholds in networks with different density nodes.…”

A Recent Study on Routing Protocols in UWSNs

“…AMCTD [16] is an earlier protocol which maximizes the network life time due to exploits the adaptive mobility of courier nodes. AMCTD'S performance is far better than EEDBR and DBR, however it had deficiency which further removed by an Improved Adaptive Mobility of Courier Nodes in Threshold-Optimized DBR Protocol (iAMCTD) which is routing protocol overcome to AMCTD uses forwarded function for time critical applications for UWSN [17].…”
