Abstract: 6LoWPAN consists of low power devices hat conform to IEEE 802.15.4 and uses the address scheme of IPV6. It is defined by IETF. It enables the integration of IPV6 and low power devices in a personal area network. We need this new technology in order to combine various low power heterogeneous networks and enable the embedded devices to communicate with the Internet based devices. The devices connected in the 6LoWPAN network need to route packets and transfer data and thus consider efficient routing as a major concern. Issues relating to the routing requirements and the various protocols in the area of routing in 6LoWPAN are presented in this survey.
