Research on a hardware-in-the-loop simulation method for wireless network based on OPNET

Hardware-in-the-loop (HITL) simulation method can effectively improve the accuracy and reliability of wireless network simulation, it can be used for hardware test, software test and performance optimization etc. This paper analyzes the deficiency of the OPNET´s existing external interface, and presents a HITL simulation interface based on agent (HSIBA), which is used for realizing the protocol mapping from external simulation member to OPNET´s wireless node. After the implement framework and key technology of HSIBA is given, this paper verifies that HSIBA can meet OPNET´s needs in wireless network HITL simulation.
