IPCS(Inter Process Communication Service) is a real-time communication middleware designed for warship combat battle systems based on publisher-subscriber communication model. Because IPCS was originally designed to operated under 100 Mbps network environment, increasing network speed into Gigabit environment does not linearly increase the throughput of IPCS. To solve this problem, we anaylized IPCS structure and optimized IPCS into Gigabit-Ethernet environment. We found parameters to improve IPCS based on UDP and Token-ring structure. By improving, IPCS has reliability and higher throughput than TCP although IPCS is based on UDP.

This paper introduces an Irregular Repetition Slotted ALOHA (IRSA) with Particle Swarm Optimization (PSO) approach for improving energy efficiency in Industrial Internet of Things (IIoT) networks. The proposed approach combines the simplicity and scalability of IRSA with the optimization capabilities of PSO to enhance network performance. By optimizing the repetition patterns and slot allocations, the IRSA-PSO approach minimizes collisions and improves the overall system efficiency. Through extensive simulations, we demonstrate that the proposed approach outperforms existing protocols in terms of achieving the desired error rate while reducing energy consumption. This contribution addresses the challenges of error rate and energy efficiency in IIoT networks, providing a valuable framework for designing efficient and reliable communication protocols in IIoT applications.
