Research ArticleOpen accessIn the abstractPrioritized Experience Replay-Based Deep Deterministic Policy Gradient for Reliable Path Selection in SDN-IoT NetworksGaurav Kumar, G. S. Girisha, N. ShamanthRouting optimization is becoming prominent in Software-Defined Networks (SDN) due to the exponential growth of network traffic demands and the requirement for Quality of Service (QoS). However, reliable routing that satisfies the QoS requirements, such as end-to-end delay, packet loss, and bandwidth, remains a difficult task in SDN. To overcome this limitation, a Deep Reinforcement Learning (DRL)-based Prioritized Experience Replay-based … …Journal of Computer Science, Vol. 22, Issue 8 · 4 Aug 2026 · 1,001 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnergy and Distance Aware Multi-Objective Firebug Swarm Optimization Based Clustering and Routing in Wireless Sensor NetworksGundeboyina Srinivasalu, Hanumanthappa UmadeviIn recent years, Wireless Sensor Networks (WSNs) have received increased international attention due to advancements in the communication, electronics, and information fields. These sensor networks integrate a huge number of sensor nodes to track rapidly changing physical events. The key improvement is that these nodes can be easily positioned in any environment due to their small size. Therefore, maintaining network … …Journal of Computer Science, Vol. 19, Issue 3 · 10 Feb 2023 · 6,029 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTransTrip: A Shortest Path Finding Application for Jakarta Public Transportation using Dijkstra AlgorithmRini Wongso, Cin Cin, Suhartono, JosephGovernment of Jakarta, the capital of Indonesia, highlighted congestion as one of the issues that must be addressed immediately. The high population of Jakarta increases the number of vehicles operating on the streets and causes congestion that leads to a loss of 67.5 trillion rupiah. The development of adequate public transport facilities is expected to be one of the solution, … …Journal of Computer Science, Vol. 14, Issue 7 · 29 Jun 2018 · 9,328 accessesView PDF Cite
