Real-time industrial application requires routing protocol that guaranteesdata delivery with reliable, efficient and low end-to-end delay. ExistingRouting(THVR) [13] is based velocity of Two-Hop Velocity and protocol relatestwo-hop velocity to delay to select the next forwarding node, that has overheadof exchanging control packets, and depleting the available energy in nodes. Wepropose a Real-Time Reliable Data delivery based on Virtual Coordinates Routing(RRDVCR) algorithm, based on the number of hops to the destination rather thangeographic distance. Selection of forwarding node is based on packet progressoffered by two-hops, link quality and available energy at the forwarding nodes.All these metric are co-related by dynamic co-relation factor. The proposedprotocol uses selective acknowledgment scheme that results in lower overheadand energy consumption. Simulation results shows that there is about 22% and9.5% decrease in energy consumption compared to SPEED [8] and THVR [13]respectively, 16% and 38% increase in packet delivery compared to THVR [13] andSPEED[8] respectively, and overhead is reduced by 50%.
