Abstract

IPv6 over Low Power Wireless Personal Area Network (6LoWPAN) connects the highly constrained sensor nodes with the internet using the IPv6 protocol. 6LoWPAN has improved the scalability of the Internet of Things (IoTs) infrastructure and allows mobile nodes to send packets over the IEEE 802.15.4 wireless network. Several mobility managements schemes have been suggested for handling the registration and handover procedures in 6LoWPAN. However, these schemes have performance constraints, such as increased transmission cost, signalling overhead, registration, and handover latency. To address these issues, we propose a novel cluster-based group mobility scheme (CGM6) for 6LoWPAN. To reduce the signalling cost in the CGM6 scheme, we propose to combine the functions of the Authentication, Authorization and Accounting (AAA) server and Local Mobility Anchor (LMA) in AMAG6 (AAA + MAG for 6LoWPAN). AMAG6 acts as a cluster head and exchange its information directly with its neighbouring AMAG6 during the mobility. Furthermore, AMAG6 is responsible for the binding and authentication process. To reduce the transmission cost, we also propose enhancements in registration and Handover procedures. The performance of CGM6 is evaluated through extensive simulations. The simulation results show that CGM6 has reduced the handoff latency by 32%, registration delay by 11% and transmission cost by 37% compared to the state-of-the-art mobility management schemes.
