Improved Adaptive Cooperative Routing in Underwater Wireless Sensor Networks
2015
In Underwater Wireless Sensor Networks (UWSNs), reliability is an important factor which effects the overall performance of the network. As the underwater environment is noisy and due to multipath fading and poor link quality, the reliability of the network and data integrity is affected. With cooperative routing, the reliability and the integrity of the data is improved. In this paper two relay nodes and a master node is selected for the transmission of data from source to the sink. Master node is selected among the neighbouring nodes which has low depth, high residual energy and must lie outside the threshold defined. On the basis of depth threshold of source node and the master node, two relay nodes are selected for the retransmission mechanism. Simulation results show that IACR achieves better results with respect to packet acceptance ratio, throughput, network lifetime and packet drop as compared to ACE.
