Data-driven application workflows that leverage compute capabilities and hosted services near the network edge can support latency-sensitive and critical applications in emerging areas such as Internet of Things (IoT) and smart infrastructure. However, distributed instantiation and execution of these workflows using resources across service providers and datacenters can be challenging. In this paper,...
As more and more reusable web services are published on the Internet, how to help users quickly identify appropriate candidate services has become an increasingly critical challenge. Most of the current research efforts on service discovery rely on syntax and semantics-based service matchmaking. In contrast, this paper presents a novel way of applying network routing mechanism to facilitate service...
Traffic from mobile wireless networks has been growing at a fast pace in recent years and is expected to surpass wired traffic very soon. Service providers face significant challenges at such scales including providing seamless mobility, efficient data delivery, security, and provisioning capacity at the wireless edge. In the Mobility First project, we have been exploring clean slate enhancements...
The Internet is approaching a historic inflection point with online wireless and mobile devices to far surpass wireline devices. The current Internet architecture and dominant protocols such as TCP/IP, which were designed and evolved on networks of fixed-hosts, are ill equipped for this fundamental shift. In this paper we introduce an alternative future Internet architecture, MobilityFirst, that prioritizes...
Mobile devices are expected to become the Internet’s predominant technology. Current protocols such as TCP/IP were not originally designed with mobility as a key consideration, and therefore underperform under challenging mobile and wireless conditions. MobilityFirst, a clean slate architecture proposal, embraces several key concepts centered around secure identifiers that inherently support mobility...

Large-scale wireless sensor network (WSN) deployment is a major challenge for Internet of Things (IoT) to connect physical world through sensors or tags at the scale of billions of objects. Today's WSNs normally use dedicated gateways to bridge sensors and IP networks. The installation and maintenance of such a WSN infrastructure are expensive and non-scalable. As the number of smart phone users grows...
Vehicular networking, both vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I), is an increasingly important usage scenario for future mobile Internet services. Radio technologies such as 3G/4G and WAVE/802.11p now enable vehicles to communicate with each other and connect to the Internet, but there is still the lack of a unifying network protocol architecture for delivery of services across...
In the emerging paradigm of pervasive computing, applications change their behaviors in response to their environmental context, which is provided by the smart objects in the Internet of Things (IoT). IoT envisions building a convergent platform to share dynamic data from smart objects and middleware services that process the data. In this paper, we show that the MobilityFirst Future Internet Architecture...
This paper presents a detailed description of content delivery techniques used in the proposed MobilityFirst (MF) clean-slate future Internet architecture now under development. The MF architecture addresses the requirements of mobile content delivery using the following basic design elements: (1). mapping of human readable names to “flat” globally unique identifiers (GUID's) which are used as the...
Machine-to-machine (M2M) communication represents an important new class of applications for the future “Internet of Things (IoT)”. The IoT scenario requires scalable connectivity to billions of embedded devices such as sensors, RFID's and machines. Current sensor networking solutions involve the use of gateways for hierarchical access to sensor devices, but this approach leads to specialized M2M...
