| In modern war, the communication mode of military command system has developed into a multi-stage, multiple joint and multi-means of communication synthesis communication network system. It can be realize command control, communication control, battlefield surveillance, message processing through this network.Wireless network technology has become a key technology in the communication network. At first, this paper provides the composition, structure and principle of wireless network. And the performance of wireless network is analyzed. Secondary, the construction of wireless network is analyzed, the TDMA technology which is used in the communication network is described. The hierarchical network communication protocol is designed based on the characteristic of wireless network, including the design idea and base function. This paper provided the related error correction and error detection algorithm, reducing the high error rate which caused by the unstable channel in the wireless data transmission. The special frame-losing processing frame is designed to reduce the problem of frame-losing which are caused by the special reason of the broadcasting station. After that the simulation test of some key technologies-wireless network, error correction algorithm and frame-losing processing frame-are carried out by constructing the simulation platform and designing the developing, simulating and testing software. At last, the multi-node network communications of all system are fulfilled by designing the communication network system software based on the Visual C++ in windows system platform.The main application value of this topic lies in: implementing network and maintaining steady operation of network through designing communication protocol of wireless network and communication pattern of wireless network, error correction processing of wireless data. It can provide a reliably, highly effective wireless network data platform for the military command communication system. |
