Accomplishing a reliable transmission of data takes a vital role in Industrial Wireless Sensor Networks (IWSN) so as to overcome the practical messes in monitoring the industrial equipment deployed in a real-time scenario. The parameters sensed from each machine get transferred over to the controlling device through a multi-hop fashion in a networking environment assisted by a ZigBee standard. Taking concern over the information transmission, the PAN coordinator deployment scores a key impact in realizing a full-fledged proficient IWSN. PAN holds the responsibility of stipulating channels for communicating sensed information from sensing devices to the controlling authority. Allocating channel with proficiency certainly, mitigates the energy exhausted for transmission. In a case of acquiring a poor channel for transmitting the sensed information, then congestion occurs that consequently leads to a congested state of a channel. The traffic accustomed out of sensing some sorts of critical criterion should get transmitted with an utmost preference amidst of regular traffic. At this juncture, the latency for transmitting other data packets significantly surges and hence, the energy disbursed with respect to waiting also increases. Many techniques prevailing at presents such as IEEE 802.15.4 and data gathering approach that involves in relying upon sensed information through a multi-fold relaying scheme does not cater a sufficient channel slot without any congestion and utilizing those freed up channels for other highly prioritized sensing devices to transmit information. In order to get rid of these issues, this paper presents an effectual Priority based Scheduling with a Slot based Route Discovery (PCS-SRD) methodology. The procedure of route discovery gets accomplished on the basis of pre-defined slots and hence, the concept of energy conservation gets fulfilled. Likewise, effectiveness in transmitting information with an extreme urgency traverses the network deprived of subjecting towards any congestion through a high prioritized channel. Hence, the proficiency of the devised mechanism gets compared with those prevailing methodologies in terms of reliability, average delay, and throughput and power consumption.
