Gateway Architecture Design of Wire/Wireless Heterogeneous Network Integration

Facing the monitoring of some mobile, rotated or dangerous objects in the industry environment and the requirements of wireless data communication, this paper first introduces various methods of heterogeneous network integration and the system structure of wire/wireless heterogeneous network. Then design a model of the heterogeneous network integration gateway between IEEE802.15.4a and Profibus-DP. It includes the designs of intermediate layer and mapping mechanism, and in detail describes the virtual station data structure which can indicate the data change of wireless terminal station, and the mapping relationship between this data structure and wireless stations.
