Mobility support for Proxy Mobile IPv6 in TRILL-based mobile networks

In mobile networks, the Proxy Mobile IPv6 (PMIP) scheme tends to induce large tunneling overhead and non-optimal routes for data packet delivery. To overcome such limitations, we propose the use of PMIP for mobility control in mobile networks based on the Transparent Interconnection of Lots of Links (TRILL). In the proposed scheme, each edge Routing Bridge (RB) in the TRILL network will function as Mobile Access Gateway (MAG) of PMIP, and an enhanced Local Mobility Anchor (eLMA) is used at the gateway of TRILL mobile network. With such eLMA, the control and data plane are separated, and the data path is optimized in PMIP. Moreover, each data packet in PMIP is encapsulated with the TRILL header, instead of using the IP-in-IP header. By numerical analysis, we show that the proposed scheme can give better performance than the existing schemes in terms of traffic processing overhead and total transmission delay.
