摘要：Wireless information transmission through the ocean is one of the enabling technologies for the development of future ocean-observation systems and sensor networks. Pervasive Underwater sensor networks (UWSNs) establish the communication in underwater for various applications such as natural exploration, surveillance, resource management etc. The prime factors to achieve effective communication through acoustic channel of these networks are the Energy and Reliability. owing to the long propagation delay and high error rate of acoustic channels, it is very challenging to provide reliable data transfer for UWSN.For throughput and robustness of networks it is proved to be that network coding is an effective coding technique. So this paper proposes a communication model called EERCM that utilizes a Multipath routing with network coding to improve reliability and energy efficiency in UWSN.By adopting the hop by hop transmission method to form multipath, this model reduces the energy consumption of acoustic nodes to achieve energy efficiency and without framing of end-to-end paths, each node maintains the path information for local nodes to the next hop node and during the hop node election neighbor nodes are diverged into groups and then the sensed information is sent to the next hop node that hop to lesser sink node. So from this redundant information provides reliable communication. This model is implemented and its performances are evaluated.
