“…In 2014, Diamant R et al proposed to combine rate-compatible RS codes and the incremental redundancy hybrid automatic repeat request (IR-HARQ) protocol in Haifa port to achieve UWACS performance in terms of throughput and transmission power consumption that is superior to fixed-rate coding schemes [45]. In 2018, Khanai R et al compared the performance of IDMA-OFDM-MIMO with RS and turbo coding and found that RS codes have higher BERs than turbo codes but consume less power [46]. In 2021, Sklivanitis G et al found that a suitable combination of channel characteristics and RS codes can securely generate 256-bit encryption keys.…”

Due to the simultaneous existence of severe difficulties caused by multi-path, Doppler, and environmental noise caused by underwater acoustic channels, designing a stable and reliable underwater acoustic communication system (UWACS) is a challenging task. In addition to channel estimation and equalization, the technique of channel codes, which is capable of approaching Shannon’s capacity at a low encoding and decoding complexity, offers an efficient and reliable solution to improve the performance of the UWACS and thus draws extensive attention from the research community. By seeking a balance between communication efficiency and channel tolerance via multiple coding rate tuning, it has been recognized that the rate-compatible codes can achieve smooth rate-adaptive transmission under highly diverse underwater acoustic channel states. While there has been a substantial number of investigations on rate-compatible channel codes for the UWACS, in this paper, the research of rate-compatible channel codes has been summarized, reviewed, and compared, mainly focusing on the low-density parity-check (LDPC) and polar codes, which render flexibility in terms of code length and rate. Furthermore, typical research was evaluated and compared from the practical viewpoint of performance under real noise in a shallow water environment. Finally, problems encountered by the LDPC and polar codes for the UWACS were highlighted, and several future research issues were discussed.

“…In [8] the author has demonstrated for Additive White Gaussian Noise (AWGN) and Rayleigh fading channels in wireless sensor network the best coding rate choice a between wireless nodes. The detailed study in [9], investigates the ARQ method achieved when the code rate of the error-correcting coding technique is improved. In underwater wireless acoustic networks, due to the nodes potential energy savings the optimization of channel coding strategies has also been investigated.…”

Future Underwater communication demands high speed data transmission. Present Underwater communication can only provide a limited data rate, where the available bandwidth is limited. To increase the data rate, we simulate the MIMO-OFDM with IDMA technique. In MIMO method many transmitter and many receiver antennas are present. MIMO method offer a very high capacity which raises linearly with the numeral of antennas. Data rate increases with MIMO method, bandwidth is saved and fading is reduced with OFDM. In OFDM technique the complete sign orthogonally overlays in a frequency field that secures the bandwidth. IDMA system is constructed on interleaving procedure. In this paper different coding techniques Convolutional, RS code, LDPC code, Turbo code with IDMA OFDM MIMO technique are compared. IDMA OFDM MIMO with Turbo code, BER performance is improved up to 10-6 .

“…Two types of Securities are required for data aggregation in wireless sensor network namely Confidentiality and data integrity. The confidentiality process helps to protect the sensitive [45] data transmission and passive attacks whereas the integrity helps to reduce the compromised sensor nodes in the network. There are two types of methods such as hop by hop encryption and end to end encryption for securing the data in wireless sensor network.…”

The use of wireless sensor networks has been increasing tremendously in the past decades mainly because of its applications in military, medicine, under water survey and various other fields. Depending on the applications the sensor nodes are placed in different areas and the data sensed will be sent to the base station. The process of transmitting and receiving data sensed by the sensor nodes continues till the sensors have battery life. This leads to generate data redundancy and reduces efficiency of the network. In order to overcome the limitations faced by the wireless sensor networks, the fusion of data known as data aggregation is introduced. In data aggregation, the data sensed by the various nodes are aggregated and sent to the base station as a single data packet. In this paper, a brief review on various data aggregation methods, challenges and issues are addressed. In addition to this, performance parameters of various data fusion methods to measure the efficiency of the network are discussed. The design of single aggregator models are easy compared to the multiple aggregator models. However, the security to most of the data fusion schemes is provided by using message authentication code. It also uses public keys and symmetric to achieve end to end or hop by hop encryptions.
