This paper proposes a 6LoWPAN service model based on the IPv6-based-Anycast communication model. This model is extended into 6LoWPAN service model so that the data-centric services of WSN can be achieved efficiently in the address-centric 6LoWPAN. In the proposed service model, an IPv6 node can obtain multiple network services through one request-response interaction where multiple sensor nodes cooperate to complete all requested network services and they provide their respective network services at the same time. As a result, the delay time is shortened. In addition, the proposed service model avoids the service failure caused by dormant sensor nodes. Since users can only request the network services they are interested in, the redundant data transmission is avoided. The performance parameters of the proposed service model are analyzed, and the data results show that the performance of the proposed service model is better.

This paper proposes a scheme for connecting vehicular networks to the Internet protocol version 6‐based Internet. In this scheme, the architecture based on road domains is proposed in order to reduce the mobility handover frequency. Based on this architecture, the distributed address configuration algorithm for vehicular networks is proposed. In this algorithm, a vehicle obtains a unique address from the nearest access point (AP) without duplicate address detection. Based on this architecture, the routing algorithm based on the geographical position is proposed. The routing algorithm is performed in the link layer, and a vehicle achieves the communication with the Internet via the nearest AP. As a result, the communication delay is shortened. In this scheme, a vehicle is always identified by its home address, and during the mobility process, it does not need to be configured with a care‐of address. Therefore, the packet loss caused by the address change is avoided. Moreover, during the mobility handover process, a vehicle can receive the data from the same AP, so the packet loss rate is substantially reduced. This paper evaluates the performance of the proposed scheme, and the data results show that this scheme shortens the communication delay and lowers the packet loss.
