Hierarchical wireless network architecture for factory network

The traditional wired networks in an industrial firm often encounters large difficulties,such as the cable installation,regular maintenance and cable replacement and so on,all these results in high cost.So,in this paper,we propose an IP-based hierarchical wireless network architecture and apply some of the technologies of 6LoWPAN to it.We verify the proposed architecture via real implementation with a wireless backbone,sensor networks and a connection between those networks.And the IP-based hierarchical industrial network is indeed an advanced network for harsh industrial environments.
