Abstract
This paper discusses the design challenges associated with supporting advanced mobility services in the future Internet. The recent transition of the Internet from the fixed host-server model to one in which mobile platforms are the norm motivates a next-generation protocol architecture which provides integrated and efficient support for advanced mobility services. Key wireless access and mobility usage scenarios are identified including host mobility, multihoming, vehicular access and context addressability, and key protocol support requirements are identified in each case. The MobilityFirst (MF) architecture being developed under the National Science Foundation's future Internet Architecture (FIA) program is proposed as a possible realization that meets the identified requirements. MF protocol specifics are given for each wireless/mobile use case, along with sample evaluation results demonstrating achievable performance benefits.
