Abstract

Network Mobility (NEMO) and IPv6 over Low power Wireless PAN (6LoWPAN) protocols are the two significant important technologies in the current networking research areas and seem to be vital for the future ubiquitous environment. It can maximize the ripple effect of ubiquitous revolution due to the close correlation between NEMO and 6LoWPAN. In this paper, we propose an interoperable architecture between NEMO and 6LoWPAN. To accomplish our goal we have enhanced the routing protocol: An extended routing scheme for mobile routers to support mobility in 6LoWPAN sensor nodes. Enhanced routing scheme performs default gateway discovery and mobile network prefix discovery operations for packet forwarding, path optimization and backup route maintenance. Simulation shows that our mechanism is capable of minimizing the routing overheads, and end-to-end packet delay.
