MobilityFirst

The MobilityFirst project was started in 2010 with funding from the National Science Foundation's Future Internet Architecture (FIA) program.  The first phase of the FIA project was carried out from 2010-14 and resulted in a new clean-slate mobility-centric architecture called MobilityFirst (MF) along with a prototype realization of the protocol stack.  The MobilityFirst project moved to the second stage with a $5M grant under NSF's Future Internet Architecture - Next Phase (FIA-NP) program announced in May 2014.  The FIA-NP project is aimed at design and evaluation of enchanced network services using the MobilityFirst protocol stack with a particular focus on the mobile data, content and internet-of-things use cases.  Another focus for the FIA-NP project is cellular-Internet convergence, with the goal of having a single unified Internet architecture which supports the needs of cellular systems including both 4G hetnet and 5G.  The project also aims to move from experimental testbed evaluation to technology trials with real-world users and applications.

The MobilityFirst project is founded on the premise that the Internet is approaching an historic inflection point, with mobile platforms and applications poised to replace the fixed-host/server model that has dominated the Internet since its inception. This predictable, yet fundamental, shift presents a unique opportunity to design a next generation Internet in which mobile devices, and applications, and the consequent changes in service, trustworthiness, and management are primary drivers of a new architecture. The major design goals of our proposed architecture are: mobility as the norm with dynamic host and network mobility at scale; robustness with respect to intrinsic properties of wireless medium; trustworthiness in the form of enhanced security and privacy for both mobile networks and wired infrastructure; usability features such as support for context-aware pervasive mobile services, evolvable network services, manageability and economic viability. The design is also informed by technology factors such as radio spectrum scarcity, wired bandwidth abundance, continuing Moore’s law improvements to computing, and energy constraints in mobile and sensor devices.

5G and MultiHoming with MobilityFirst

OUR STORY

The summer 2016 internship program at WINLAB has given us the opportunity to work on subprojects within the mobilityfirst project. Our group is made of two Rutgers ECE masters students, Xiaoyu Duan and Kiran Jatty, and one Rutgers ECE undergraduate student, Amin Masoomzadeh. Xiaoyu works on the 5G portion of the project while Kiran and Amin work on the multihoming portion.

OUR VISION

As for the multihoming subgroup, our goal is to be able to route packets to a client in a mobilityfirst network via all the networks connected to it with various splitting  algorithms. Currently we plan dualhomed network for a client. These two networks are ideally wifi and LTE. At WINLAB the hope is that one day such technology can be used for cellphones and laptops to improve the throughput of packet reception.

OUR WORK

 Subgroup 2  MultiHoming

Multihoming is the practice of connecting a host or a computer network to more than one network. This is done in order to increase reliability or performance, or to reduce cost. We aim to implement Multihoming with MobilityFirst which is the future internet architecture. The MobilityFirst project is founded on the premise that the Internet is approaching an historic inflection point, with mobile platforms and applications poised to replace the fixed-host/server model that has dominated the Internet since its inception. This predictable, yet fundamental, shift presents a unique opportunity to design a next generation Internet in which mobile devices, and applications, and the consequent changes in service, trustworthiness, and management are primary drivers of a new architecture.

       Subgroup 1
       5G Mobile Architecture

The clean-slate MobilityFirst next-generation  (5G) mobile network architecture is motivated by a historic shift of the Internet from the fixed host-server model to one in which access from mobile platforms becomes the norm. A cellular-internet convergence could be expected over the next decades. Bringing a completely flat mobile network architecture with native support for basic services such as authentication, dynamic association and handover, inter-network roaming, and disconnection tolerance becomes the first step to finish the convergence. Our work focuses on a practice of software-based LTE interoperability with OpenAirInterface eNB and Amarisoft EPC, which enbles the later design of flatted cellular network. On the other hand, a topology design of accessing multiple networks is set to test the performance.
