PROJECT TITLE :

Dynamic Node Cooperation in an Underwater Data Collection Network

ABSTRACT:

In this paper, we have a tendency to think about a sensible underwater knowledge collection network, where one destination needs to collect information from multiple underwater nodes. With the standard automatic-repeat-request (ARQ) protocol, the destination requests retransmission from each node individually without any node cooperation. We propose 2 protocols, selective relay cooperation and dynamic network coded cooperation, utilizing the fact that underwater nodes can overhear the transmission of the others. Within the selective relay cooperation, one node can be selected as a relay to transmit the information from another undecoded node in the retransmission part. In the network coded cooperation, the selected relay nodes transmit network coded packets to the destination. The relay nodes collaborating the cooperation are selected by the destination primarily based on the channel quality, as measured by the effective signal-to-noise ratio. Plus simulation results, we have a tendency to have carried out several lake tests primarily based on a full protocol implementation. Simulation and field testing results demonstrate that the proposed schemes will gain vital performance improvement compared with the standard ARQ scheme.
