For the design of a network layer routing scheme for Underwater Wireless Sensor Network (UWSN), physical layer cooperation is used in this paper which ensures energy efficiency. For achieving major goal of efficient data routing, a key factor is reliability for application-oriented UWSNs. All the nodes of network fortified by a unidirectional antenna cooperatively perform their propagation of data...
The acoustic environment suffers from a number of impairments which effect transmitted data reliability and integrity leads toward low-quality routing. Integral part of cooperative routing is reliable data delivery with trade-off energy consumption is high, because of multiple transmissions. In order to overcome this problem and getting advantage of cooperation routing, we proposed a scheme Sink Mobility...
In this paper, an energy efficient, interference and route aware (EEIRA) protocol is proposed for underwater wireless sensor networks (UWSNs). The protocol combines the direct and relay forwarding mechanisms in transmitting the packets from source to destination. The relaying process involves selection of the best relay from a set of relay nodes. A relay node having the least distance from source...
In Underwater Wireless Sensor Networks (UWSNs), reliability is one of the major concerns for large number of applications. The underwater environment is very harsh and noisy. Fading is common and unavoidable, therefore achieving reliable data transfer requires innovative routing solutions. This paper presents a energy efficient cooperative routing with varying Depth threshold (Dth) called Depth and...
This paper presents cooperative routing scheme to improve data reliability. The proposed protocol achieves its objectives, however, at the cost of surplus energy consumption. Thus sink mobility is introduced to minimize the energy consumption cost of nodes as it directly collects data from the network nodes at minimized communication distance.
Under water sensor networks(UWSNs) have attracted significantly to explore natural and undersea resources and gathering scientific data in aqueous conditions. The adverse characteristics in UWSNs communication and high cost limit the sensor nodes to spare deployment, causing delay, low propagation, power efficiency and floating node mobility. This proposed protocol is developed to handle these problems...
Underwater acoustic communications are a hastily growing field of research and engineering, which once were exclusively for military applications are now extending into commercial fields. Underwater Wireless Sensor Networks (UWSNs) appeal the research community, facing challenges as sensor nodes have energy constraint and radio signals are not suitable for underwater wireless communication. This paper...
We propose a new routing protocol MobiSink (mobile sink) for underwater sensor networks (UWSNs). We deploy the sink mobility in four horizontal regions of the network. The mobile sink moves in its own region to collect data from the transmission range sensor nodes. The transmission range of a node is calculated after fixed interval of time for mobile sink. In MobiSink nodes also take help of transmission...
Underwater Acoustic Sensor Networks are considered to provide efficient monitoring tasks in aquatic environment but due to limited battery resource of sensor nodes, network lifetime collapses. Energy balancing is the major issue in low network lifetime. High energy consumption creates energy holes and ultimately leads to shorter network lifetime. Therefore, energy consumption must be balanced to increase...
