Presenting a delay-sensitive routing algorithm for IoT-based networks

The Internet of Things (IoT) has emerged as a data storage and transmission platform that allows users to access remote computing resources. The Internet of Things (IoT) combines a set of ubiquitous, connected, and intelligent nodes to independently provide a variety of services. Routing in Internet of Things (IoT) wireless sensor networks (IoT-WSN) plays a crucial role in efficient data transmission between sensor nodes and central processing units. Due to resource constraints in these networks such as low energy, limited processing power, and low bandwidth, designing optimal routing protocols is essential to increase network lifetime and ensure reliable data transmission. In this research, the DCUR routing algorithm has been selected to improve routing in the Internet of Things. This algorithm tries to find the path with the least cost and delay. DCUR requires limited network state information that is maintained at each node. It essentially creates a delay-limited path that connects the source node to the destination node.The results of the performance analysis of the DCUR algorithm compared to MTR, OMS-LB, and RM-LB indicate significant improvements in reducing data transmission latency and managing network workload.An examination of the data transmission latency shows that the DCUR algorithm has been able to reduce the latency by 14.98% compared to the MTR algorithm, by 22.44% compared to OMS-LB, and by 27.11% compared to RM-LB. Also, DCUR has been able to reduce the number of hot spots by an average of 18.74% compared to MTR, by 30.79% compared to OMS-LB, and by 40% compared to RM-LB. This reduction in the number of hot spots represents a more even distribution of energy consumption among sensor nodes and an optimization of the communication path selection process. In other words, the reduction of hot spots has increased the lifetime of the nodes and made the IoT network more stable, improving the overall system efficiency. According to these findings, DCUR can be an effective option for optimizing IoT networks with high data volume and the need for efficient energy management, and paves the way for improving the performance of smart systems and automating digital processes.
