Wireless Sensor Networks (WSN) play a significant role in emerging technologies by enabling real-time data collection and monitoring in several applications, such as environmental monitoring, industrial automation, and smart cities. Although wireless sensor networks (WSNs) have been widely deployed in numerous fields, they encounter significant challenges due to their limited bandwidth, memory, inherited dynamic nature, and resource constrained environment. These challenges make the traditional traffic management techniques inefficient for WSNs resulting in traffic congestion, increased latency and inefficient data routing. The proposed framework consists of an SDN controller, shortest path routing algorithm, and grid topology to simulate the WSN environment. The paper evaluates the performance of the SDN approach in WSNs for traffic management by comparing it with the traditional technique. Results and simulations with improved latency, throughput and packet loss signify the potential of SDN to optimize traffic management in WSNs.
