Methods to use 6LoWPAN in IPv4 network

6LoWPAN is low power wireless personal area network based on IPv6 and IEEE802.15.4. It is used for transmission of IPv6 packets. But there are no ways for IPv4 hosts to connect 6LoWPAN, current Internet users can't use 6LoWPAN until IPv6 is deployed. In this paper, we propose the methods to use 6LoWPAN in IPv4 network so that IPv4 user can also utilize 6LoWPAN techniques.
