The cognitive mobility management based on the identifier/location split mechanism

Abstract

The mobility management of the traditional Internet consists of the location management and handover management to support movement of space and time. While with the introduction of the cognitive radio technology, the mobility management has to consider the location management, handover management, and spectrum management to deal with the mobility of space, time and spectrum. Furthermore, the cognitive radio allows the cognitive user can access to different frequencies and networks, which results in the interconnection problems due to the different network architectures. In this paper, we investigate the recent development of the new Internet architecture and mobility management, and propose a mobility management scheme in the cognitive Internet based on the Identity/Location Split (ILS) mechanism. The proposed scheme takes the cognitive mobility management as the single-interface heterogeneous handover problem, and adopts the AID (Accessing Identifier) and RID (Routing Identifier) to separate the identity and location of the traditional IP, and introduces the global mapping mechanism to maintain the relationship between the AID and RID to realize the mobility support for space, time and spectrum.
