NLBA: A novel provider mobility support approach in mobile NDN environment

To enhance seamless provider mobility support in NDN, we propose a Novel Locator Based mobility support Approach (NLBA). In this approach, we assign an unique locator to each Access Router (AR) in NDN networks, and further modify the outgoing faces field in AR´s original Forwarding Information Base (FIB), to record the mobility status and the current locator of the provider. Besides, we append an optional field to the original NDN packet, and further extend the AR with additional functionalities, such as caching or forwarding Interest packets on behalf of the provider. Our analytical investigations indicate that NLBA has lower handover cost and shorter handover latency, compared with other existing rendezvous/indirection point based mobility support approach.
