Abstract As the wireless sensor networks (WSNs) continue to evolve, it becomes more and more significant in our day-to-day lives. By using WSN technology and the basic principles of the Internet, designing an agricultural monitoring system (AMS) becomes important for improving agriculture in India. The AMS is low-power conservation with high precision, which can realize remote, real-time monitoring for unattended farmlands.WSNs are a promising approach used in AMS, but finding an optimal route discovery is more problematic due to dynamicity, heterogeneity, resource scarcity, and so on. The proposed optimized QoS-based multipath routing protocol (OQoS-MRP) for the WSNs in AMS is used to find near-optimal multi-hop communication path from sink to sensors for selecting the next hop neighbour nodes. The best case paths selection procedure is used for transferring data to sink. According to the QoS metrics, the performance of this communication protocol is evaluated and compared with the other existing protocols, namely, EE-LEACH and MRBCH. The simulation result shows that OQoS-MRP for the AMS achieves prominent data communication with reasonable energy conservation. It also reduces transmission delay and communication overhead on the basis of ensuring the outcome of the entire network.
