Summary Agriculture played a vital role in the growth of the Indian economy. New technologies can overcome the various issues in agriculture. One such ever‐growing area is Precision Agriculture (PA) with advancements in Wireless Sensor Network (WSN) technology. It finds applications in various segments of agriculture. The data packet of each application expects different services from the underlying network. Most of the techniques have not found much on service differentiation and arrival rate. Due to the dynamicity of the network, the traffic rate may get vary and load the selected paths which degrade performance expected from the network. These issues addressed by the proposed protocol employing Decision Support System (DSS) for intelligent path selection based on traffic rate. The proposed protocol outperforms in terms of minimized delay, energy consumption, achieving high throughput, and packet delivery ratio. PAwCOR performs CH selection based on node energy, subjected delay, and congestion to minimize cluster setup time and increases network life time by scheduling the nodes based on sensing error. K paths are identified based on energy, delay, and congestion cost of each path prioritizing emergency packets in response to sudden change in micro climate over non‐periodic data transmission. PAwCOR supports efficient utilization of the network bandwidth by selectively using single path or multiple paths based on packet arrival rate.
