Abstract

Reliable transmission is one of the most critical requirements in industrial distributed control systems. This paper proposes a multipath-based reliable routing protocol that can guarantee a specified end-to-end target packet reception rate. In the route discovery phase, the path has highest end-to-end packet reception rate is set up and chosen to transmit data packets. To maintain the target packet reception rate, the destination node monitors periodically its actual packet reception rate and sends a feedback control message to the source if its reception rate drops below the target rate. If the source node receives the feedback message, it adds more paths while maintaining the existing paths to keep the end-to-end packet reception rate above the specified target rate. The performance of the proposed protocol has been analyzed by simulation using QualNet simulator. The simulation result has shown that the proposed protocol has a better packet reception rate than the previous routing protocols and maintains a target packet reception rate in a network where the amount of traffic changes dynamically.
