Abstract
In Industrial Automation and Process Control (IAPC) the sensory measures have the time validity. Hence, these measures should be delivered to control center within predefined deadline time so that the necessary action may be initiated. The real-time wireless sensor networks (WSNs) routing protocols are well suited to IAPC. They follow the spatiotemporal communication strategy for in-time data delivery. The existing WSNs real-time routing protocol selects forwarding node based on desired deadline time and the end-to-end distance. Their reliability of in-time data delivery suffers due to void area problem. In this paper a Reliable Realtime Routing (RRR) protocol has been proposed and analyzed. The proposed protocol improves the end-to-end deadline packet reception rate. Moreover, the reliability of in-time data delivery is improved by regulating the transmission energy as it faces void area. The simulation results show that there is significant improvement towards reliable end-to-end deadline time data delivery.
