All-IP communication between wireless sensor networks and IPv6 networks based on location information
The paper proposes a scheme on achieving all-IP communication between wireless sensor networks and IPv6 networks based on sensor nodes' location information. The paper proposes the sensor node's IPv6 address structure based on location information, the IPv6-address configuration algorithm based on the proposed IPv6 address structure, the mobility handoff algorithm and the routing algorithm in the link layer. The location information of sensor nodes is utilized to achieve the IPv6-address configuration algorithm and the routing algorithm. In the mobility handoff algorithm, neither does a mobile sensor node need a care-of address during the mobility process, nor is involved in the mobility handoff process. Therefore, a mobile sensor node's power consumption is reduced and the life span is prolonged. The paper analyzes the performances of the proposed scheme and the existing schemes, and the analytical data show that the performance of the proposed scheme is better.
