| For a long time, the research on the characteristics of computer network system is very hot. It has been made great development on the Competition-collision cancellation access control mode, which is a very important way of access control on the star network. Depending on the operating mechanism of the star network, C-CC mode is divided into type I to VI system model, and has made some achievements on the theoretical study of mathematical modeling and performance evaluation on them. But it still on the exploring stages for practical application.In recent years, with the rapid development and increasingly sophisticated of microelectronics micro-systems, wireless communications, and signal processing technology. As the core networking technology the wireless sensor networks (Wireless Sensor Networks, referred WSN) technology has been developed rapidly and gradually changing the way of our daily life. So the WSN collected a lot of data, how to deliver the data to the backbone network efficiently and reliably is very important.The purpose of this paper is to merge the C-CC star network which is large capacity, high efficiency, simple and easy expansion with wireless sensor networks which are self-organization, dynamic, application, low bit rate and data-centered. First, we analyze the C-CC star network, WSN and the gateway which connect C-CC star network and WSN, by system model. Considering the cost problem, we choose the mature OMNeT++ simulation platform to build the system to realize the interconnection between the C-CC star network and WSN. Then through the OMNeT++ network simulation platform, we get some important performance parameters such as the average delay of packets, the average queue length of central node and so on. And compared the simulation experiment results with the existing theoretical results, then evaluate it. The results show the similarity between simulation results and theoretical results, verify the validity of the theoretical results. |
