Owning to the vital resources in a harsh and unforeseeable aqueous environment, the network stability and reliability in underwater acoustic wireless sensor networks (UAWSNs) have paramountsignificance. Stability guarantees the consistent performance of the network node's energy consumption,avoids data loss, packets reception time and network lifetime. The reliability of packet ensures the selectionof favorable channel and avoid adverse channel effects, and the vital information is easily

This paper introduces two new routing schemes for UAWSNs; stable and reliable short-pathrouting (RSPR) scheme, and cooperative reliable short-path routing (CoRSPR). In RSPR routing, the destination node is selected by considering the weighting function parameters of the highest residual energy,highest SNR, lowest euclidean distance, and least number of neighbor nodes. The scheme reduces the energyconsumption due to less number of nodes contribution in the packet advancement process. The RSPRprotocol is a non-cooperative technique, where the packets are delivered using a single-path link, whichmay not be consistently reliable. To cope with this issue, the CoRSPR protocol is proposed, which takescooperative routing into account, for stable and reliable data delivery. In cooperative routing, the receptionof more than one copy of the data packet is involved by the destination node. This reduces the unfavorablechannel effects during data delivery. The simulation results show that the proposed schemes achieve betterperformance in terms of dead nodes, energy left in the battery, packet acceptance ratio, successful receivingof packets at the sink and E-2-E delay.
