Critical data real-time routing in industrial wireless sensor networks

Recent developments in the field of micro-electro mechanical systems and wireless sensor networks made revolutionary changes in industrial automation and process control. However, harsh and complex industrial environment pose great challenges toward real-time and reliable wireless communication. This necessitates a routing protocol that fulfils the industrial current real-time, reliable routing needs and opens the door for new applications that may arise in future. This study presents critical data reliable routing protocol for industrial real-time applications. That dynamically selects the reliable relay node by considering the data type, deadline time along with the recent parameters of the network. These parameters are selected in such a way that the critical data forwarding follow shorter path over speedy, reliable links and non-critical data forwarding follow the path over energy efficient nodes. In this way, the relay node selection process balances the network load that the shorter path remains available for the shorter deadline-time critical data. The results show improvement in timeliness data delivery along enhanced network life. As far as a node failure is concerned, the forwarding node fails to access potential relay node. Therefore, following transmission energy regulation mechanism optimises this problem with enhancing timeliness data delivery.
