A hierarchical scheme on achieving all-IP communication between WSN and IPv6 networks

The paper proposes a hierarchical scheme on implementing all-IP communication between wireless sensor networks and IPv6 networks. The paper proposes the cluster-tree architecture for all-IP wireless sensor networks which is consistent with the IPv6 Internet architecture. Based on the cluster-tree architecture, the paper proposes the hierarchical IPv6 address configuration algorithm where the IPv6 configuration for cluster members in different clusters can be performed simultaneously, so the IPv6 configuration delay is shortened. Based on the proposed cluster-tree architecture and the IPv6 address configuration algorithm, the paper proposes the hierarchical routing scheme in the link layer where the intermediate nodes only need to deal with the frame header in the link layer without processing the headers in the above layers, so the routing delay is shortened and the power consumption is reduced. From both theoretical perspective and simulative perspectives, the paper analyze the performance parameters of the proposed scheme. And the data results show that the performance of the proposed scheme is better.
