Inter-PAN Mobility Support for 6LoWPAN

This paper proposes Inter PAN mobility support for 6LoWPANs moving within an IP domain. In order to reduce the processing and signaling load on the mobile node (MN) caused by the movement, the mobility related processing of 6LoWPAN nodes is delegated to the existing PAN entities with less power constraints. Also this mobility support mechanism aims to reduce Inter-PAN Handover time by providing the information about the frequencies of surrounding PANs in the vicinity of the border nodes of the PAN. The signaling cost incurred is evaluated in terms of speed through analytical modeling and the performance is compared with HMIPv6. The results indicate a fair amount of reduction of signaling bandwidth achieved through the proposed support.
