Intra-MARIO MARIO A Fast Mobility Management Protocol for 6LoWPAN
Abstract: One of the major challenges in 6LoWPAN is to provide continuous services while mobile nodes' movements with minimizing network inaccessible time caused due to handoffs. Even though MIPv6, HMIPv6, and PMIPv6 are commonly accepted standards to address this in IP networks, they cannot inherently avoid the degradation in communication quality during handoff, since they are not designed with consideration of constrained node networks like 6LoWPAN. In this paper, we propose a new fast mobility management protocol for 6LoWPAN, named intraintra MARIO. To minimize handoff delay and enhance service availability, intra-MARIO intra introduces three important components, which are a fast rejoin scheme for handoff ndoff management with an adaptive polling based movement detection and multi-hop hop pointer forwarding schemes for location management. To justify the effectiveness, we have conducted extensive simulations by comparing intraintra MARIO with prior schemes like a ba basic sic mobility management scheme and a PMIPv6-based based protocol. We then implement intra intra-MARIO MARIO on top of our 6LoWPAN platform (SNAIL) and evaluate the performance of intra intra-MARIO. MARIO. The results highlight that intra-MARIO MARIO reduces overall handoff delay with low power powe consumption and minimizes packet losses during handoffs, compared to prior mobility protocols.
