As the number of devices that gain connectivity and join the category of smart-objects increases every year reaching unprecedented numbers, new challenges are imposed on our networks. While specialized solutions for certain use cases have been proposed, more flexible and scalable new approaches to networking will be required to deal with billions or trillions of smart objects connected to the Internet. With this paper, we take a step back looking at the set of basic problems that are posed by this group of devices. In order to develop an analysis on how these issues could be approached, we define which fundamental abstractions might help solving or at least reducing their impact on the network by offering support for fundamental matters such as mobility, group based delivery and support for distributed computing resources. Based on the concept of named-objects, we propose a set of solutions that network and show how this approach can address both scalability and functional requirements. Finally, we describe a comprehensive clean-slate network architecture (MobiityFirst) which attempts to realize the proposed capabilities.

As the amount of mobile devices populating the Internet keeps growing at tremendous pace, context-aware services have gained a lot of traction thanks to the wide set of potential use cases they can be applied to. Environmental sensing applications, emergency services, and location-aware messaging are just a few examples of applications that are expected to increase in popularity in the next few years. The MobilityFirst future Internet architecture, a clean-slate Internet architecture design, provides the necessary abstractions for creating and managing context-aware services. Starting from these abstractions we design a context services framework, which is based on a set of three fundamental mechanisms: an easy way to specify context based on human understandable techniques, i.e. use of names, an architecture supported management mechanism that allows both to conveniently deploy the service and efficiently provide management capabilities, and a native delivery system that reduces the tax on the network components and on the overhead cost of deploying such applications. In this paper, we present an emergency alert system for vehicles assisting first responders that exploits users location awareness to support quick and reliable alert messages for interested vehicles. By deploying a demo of the system on a nationwide testbed, we aim to provide better understanding of the dynamics involved in our designed framework.
