On the Selection of Transmission Range in Underwater Acoustic Sensor Networks

Energy is a unique characteristic of Underwater Acoustic Sensor Networks (UASNs) which is limited in features and a basic point on which the whole network depends. On the basis of efficient energy utilization, we propose a routing protocol Enhanced and Efficient Balance energy consumption in Data Gathering (EEBDG) for UASNs. This routing scheme EEBDG, works for large scale area networks efficiently and effectively by balanced energy consumption. EEBDG removes the deficiency of previous routing scheme in which mixed routing performs all over the network which is not possible in real world when network size increases. By the increase in area of a network, we avoid the direct transmission mode using only hop by hop transmission. The contribution of our work is to extend network lifetime with large scale in the form of increased nodes and dimension, minimize energy utilization by balanced energy consumption, increased number of packets transfer. Our trade-off is packet drop ratio when number of nodes is small in sparse networks, but when the number of nodes increases our packets drop is also improved.

“…The main sources of the noise include turbulence, shipping, waves and thermal noise [ 13 ]. Moreover, packet loss depends on the traversed distance and the transmission power of the underwater acoustic signal [ 14 , 34 ]. Thus, packet forwarding is more likely to be successful if packets are relayed over multiple short distances instead of traversing over long distances.…”

Increasing attention has recently been devoted to underwater sensor networks (UWSNs) because of their capabilities in the ocean monitoring and resource discovery. UWSNs are faced with different challenges, the most notable of which is perhaps how to efficiently deliver packets taking into account all of the constraints of the available acoustic communication channel. The opportunistic routing provides a reliable solution with the aid of intermediate nodes’ collaboration to relay a packet toward the destination. In this paper, we propose a new routing protocol, called opportunistic void avoidance routing (OVAR), to address the void problem and also the energy-reliability trade-off in the forwarding set selection. OVAR takes advantage of distributed beaconing, constructs the adjacency graph at each hop and selects a forwarding set that holds the best trade-off between reliability and energy efficiency. The unique features of OVAR in selecting the candidate nodes in the vicinity of each other leads to the resolution of the hidden node problem. OVAR is also able to select the forwarding set in any direction from the sender, which increases its flexibility to bypass any kind of void area with the minimum deviation from the optimal path. The results of our extensive simulation study show that OVAR outperforms other protocols in terms of the packet delivery ratio, energy consumption, end-to-end delay, hop count and traversed distance.

“…In practice, a minimum transmit power level is always required [31], independent of the link distance l . The total electric power for a single transmit attempt over the acoustic link can be written as

P_{t o t a l} = P_{t x}^{e l} + \max (() P_{P A}, P_{P A}^{m i n}) + P_{r x}^{e l} (Watts),

Underwater acoustic networks (UAN) allow for efficiently exploiting and monitoring the sub-aquatic environment. These networks are characterized by long propagation delays, error-prone channels and half-duplex communication. In this paper, we address the problem of energy-efficient communication through the use of optimized channel coding parameters. We consider a two-layer encoding scheme employing forward error correction (FEC) codes and fountain codes (FC) for UAN scenarios without feedback channels. We model and evaluate the energy consumption of different channel coding schemes for a K-distributed multipath channel. The parameters of the FEC encoding layer are optimized by selecting the optimal error correction capability and the code block size. The results show the best parameter choice as a function of the link distance and received signal-to-noise ratio.
