  Real-time industrial application requires routing protocol that guarantees
data delivery with reliable, efficient and low end-to-end delay. Existing
Routing(THVR) [13] is based velocity of Two-Hop Velocity and protocol relates
two-hop velocity to delay to select the next forwarding node, that has overhead
of exchanging control packets, and depleting the available energy in nodes. We
propose a Real-Time Reliable Data delivery based on Virtual Coordinates Routing
(RRDVCR) algorithm, based on the number of hops to the destination rather than
geographic distance. Selection of forwarding node is based on packet progress
offered by two-hops, link quality and available energy at the forwarding nodes.
All these metric are co-related by dynamic co-relation factor. The proposed
protocol uses selective acknowledgment scheme that results in lower overhead
and energy consumption. Simulation results shows that there is about 22% and
9.5% decrease in energy consumption compared to SPEED [8] and THVR [13]
respectively, 16% and 38% increase in packet delivery compared to THVR [13] and
SPEED[8] respectively, and overhead is reduced by 50%.
