Delay Tolerant Networking*
|
Challenge The protocols of today’s Internet operate poorly when faced with operating environments characterized by very long delay paths, frequent network partitions, and severe power or memory constraints.
Solution A network architecture and application interface structured
around optionally-reliable asynchronous message forwarding, with limited expectations of end-to-end connectivity and node resources.
Potential Impact DTN enables a range of applications to be used in environments with poor connectivity—from email and voicemail to offline search engine queries, electronic form filling, and "instant-enough messaging"—at a reduced cost.

Rural Connectivity Platform
|
Challenge There’s a tremendous need for affordable, robust wireless networking in rural areas of the developing world. Existing infrastructure that is useful in high-density areas, where costs can be spread over many users (notably, cellular telephony), is not appropriate for sparsely populated rural regions.
Solution Build, test and deploy an integrated ‘combox’ prototype
develop application proxies and robust comms middleware based on Delay Tolerant Networking extended 802.11 based on UCB/TIER studies.
Potential Impact An robust, affordable, wireless communications infrastructure for rural areas of emerging regions.

Declarative Networking
|
Challenge Any widely-distributed system needs to track its participating nodes, and be able to send messages among those nodes. This facility is called an overlay. It is difficult to design, build, and deploy an overlay suited to a particular application and environment.
Solution P2 is a system that uses a high-level declarative language to express overlay networks in a highly compact and reusable form.
Potential Impact This approach could provide not only simpler, safer pecifications for network protocols, but also the ability to query, monitor and control all aspects of the network' distributed state.

Communication Efficient Tracking of Distributed Triggers
|
Challenge Enable alerts to be fired when unhealthy conditions are detected across a set of distributed monitors, without using much bandwidth.
Solution We design protocols for the monitors to communicate with a semi-centralized coordinator. The coordinator tells monitors how much data to send, and with what accuracy, so that the coordinator can fire triggers accurately whenever global conditions become unhealthy.
Potential Impact Fills an important gap in today’s proposals for large-scale distributed monitoring.

Diamond
|
|
The goal of Diamond is to enable interactive search of terabyte-scale, non-indexed collections of complex data (such as photo collections, satellite pictures and medical images) by exploiting recent advances in active disk technology.

Dynamic Physical Rendering
|
|
In the Dynamic Physical Rendering Project, researchers at the Intel Pittsburgh Lablet and Carnegie Mellon University are jointly exploring a new form of smart matter which would be composed of myriad tiny robots acting together for telepresence, teleoperation, material handing/manipulation, locomotion, and distributed sensing. "Ensembles" of thousands to millions of robots would form physical analogs of virtual shapes which human senses would accept as real, eliminating cumbersome virtual reality gear and viewing angle limitations now present for most 3D visualization and telepresence applications. Likewise, such ensembles would act as reconfigurable, general-purpose robots capable of many forms of locomotion and object manipulation.

Internet Suspend/Resume
|
|
Internet Suspend/Resume is a new approach to mobile computing in which a user’s computing environment follows the user through the Internet as he or she travels. Today, when a laptop computer is closed, the user’s execution state is suspended to disk. When the user moves the laptop to a new physical location, the user may re-open the laptop, and resume working in the same environment that was active at the time of suspend. The goal of the ISR project is to achieve the same effect without requiring the user to transport physical hardware.

Log-Based Architectures
|
|
The Log-Based Architectures (LBA) project focuses on developing extensions for many-core processors that enable efficient logging and extraction of run time execution events and demonstrating the benefits of such extensions for performance, debugging, security and recovery.

Activity Recognition
|
|
The Activity Recognition project uses sensors and statistical processing to recognize and reason about a wide range of human physical activity. Techniques under exploration include sensing at very high densities, automatically identifying features relevant to activities, mining common sense and using it in building activity models and localizing anomalies in time series data. Driving applications for the project are assisted care, physical workflow analysis and activity-aware electronics.

Platform Location Capability
|
|
The PLC project is investigating how new sensors can improve location estimation in mobile platforms and exploring the possibility of mapping indoor environments without any prior knowledge. A second thread of PLC is to engage with and transfer location technology to Intel product groups.

Mobile Sensing Platform (MSP)
|
|
The Mobile Sensing Platform is an integrated sensing and inference platform. The research goals are to build new multi-modal sensing hardware and to develop machine learning techniques for inferring context from the raw sensor streams. We are focusing on building probabilistic models for activity inference and localization using the MSP data and investigating ways to implement these algorithms on the platform itself.
