Abstract: We discuss challenges and solutions to enable ultra low power communication systems. In the field of sensor networks, this question has been investigated for multiple decades now. However, only the combination of technological and algorithmic methods eventually helps designing next generation systems. Using the application scenario of wildlife monitoring, in particular bats, explore the need for novel solutions given the high reliability requirements and weight restrictions. We go stepwise through a series of hardware, signal processing, and coding solutions that we developed. Our concepts have been explored both in large-scale simulation as well as in first field experiments.

Abstract: For more than two decades since the rise of the World Wide Web, the “Notice and Choice” framework has been the governing practice for the disclosure of online privacy practices. The emergence of new forms of user interactions, such as voice, and the enforcement of new regulations, such as the EU’s recent General Data Protection Regulation (GDPR) promises to change this privacy landscape drastically. In this talk, I will discuss the challenges towards providing the privacy stakeholders with privacy awareness and control in this changing landscape. I will also present our recent research on utilizing AI to analyze privacy policies and settings.

Abstract: This talk presents the challenges and opportunities of building a city-scale low-power wireless internet-of-things. We build upon low-power wide-area networking (LP-WAN), a technology that enables low-cost devices with a 10-year battery to communicate at few kbps to a base station, kilometers away. Yet, deploying LPWANs in large urban environments is challenging, given the sheer density of nodes that causes interference, coupled with attenuation from buildings that limits signal range. I present Choir [SIGCOMM '17], a system that overcomes these challenges despite the limited capabilities of base station and client hardware. Choir proposes novel techniques, that disentangle and decode large numbers of interfering transmissions at a simple, single-antenna LP-WAN base station. I also present Charm [IPSN'18 best paper] that shows how teams of LP-WAN base stations can collaborate to decode signals from extremely far away clients even if their signals are undetectable at any single base station. Beyond communication, I also touch upon the opportunities of an omnipresent low-power Internet. I present two solutions RF-Wear [UBICOMP '18] and WiSh [MobiSys'18] that make our own bodies and clothes shape-aware and connected to the Internet for wireless and seamless fitness and health monitoring.

Abstract:Mobile autonomous systems are posed to deeply impact in manufacturing, space exploration, rescue, defense, transportation, and everyday life. For example, fleets of autonomous air-ground vehicles employed in emergency, situation-awareness, and surveillance missions. Air vehicles can cover a large area with high speed being able to be present in both time and space while they have limited energy and autonomy. On the other hand, ground vehicles have long endurance and are capable of covering relative locations with greater accuracy, yet restricted to traveling on the road network. Combining the strengths of air and ground vehicles can enable new scenarios. Air vehicles can take a timely view of the disaster area to assess the severity of damage and can inform ground vehicles about the road network conditions around the emergency or accidental sites. Air vehicles may serve as relay points and be equipped (i.e. GPU) to serve as mobile edge-computing nodes, thus supporting air-ground communications and computational needs. Currently, these systems, are mostly self-contained data and AI-based applications operating on the same node, however there is an emerging need for cooperation, communication, and coordination as "self-contained" and purely "cloud-based" solutions may not be sufficient to handle growing task sizes and complexity. Intel estimates that each driver-less car will produce about 4TB of data every day. The majority of such data will be consumed locally, yet some will be transmitted for further processing and to enrich the global driving knowledge and/or trigger human actions.
In this talk I will describe some of the challenges exposed by air-ground mobile edge and propose some of the possible approaches and solutions for connectivity and data dissemination.

Abstract: Boundless VR/AR experiences are mobile, immersive, photorealistic, and ultra-responsive (low latency). Such experiences are possible through a split processing architecture that partitions the workload intelligently between a mobile device and powerful edge servers accessed over 5G. This architecture has many benefits, such as reliable anywhere anytime usage and ease of use with no setup or wires. It is only possible because of low-latency, high-bandwidth 5G networks. The solution offers the best of both worlds – boundless mobile VR/AR experiences with photorealistic visuals in a sleek, affordable headset.

Abstract: We attempt to make two arguments in this essay. First, through a case study of a mobile phone based voice-media service we have been running in rural central India for more than six years, we describe several implementation complexities we had to navigate towards realizing our intended vision of bringing social development through technology. Most of these complexities arose in the interface of our technology with society, and we argue that even other technology providers can create similar processes to manage this socio-technological interface and ensure intended outcomes from their technology use. This is different from the typical laissez-faire assumption that market fueled rapid scaling of technology will find a way to lead to positive social development outcomes without any dedicated efforts to manage the socio-technological interface. We then build our second argument to find an approach that can ensure that the organizations behind both market driven technologies and those technologies that are adopted by the state, pay attention towards responsibly managing the socio-technological interface. We advocate for the technology engineers and researchers who work within these organizations, to take up the responsibility and ensure that their labour leads to making the world a better place especially for the poor and marginalized. We outline possible governance structures that can give more voice to the technology developers to push their organizations towards ensuring that responsible outcomes emerge from their technology. We note that the examples we use to build our arguments are limited to contemporary information and communication technology (ICT) platforms used directly by end-users to share content, and hence our argument may not generalize to other ICTs.

Several elements of their work have also been adopted by government departments in India for scaleup, and have influenced the use of ICTs for development within many international aid and development organizations.
Abstract: Applications in a cloud environment tend to be micro-services that talk to each other via APIs (typically RESTful), are loosely coupled and rapidly changing. Dependencies between these applications can help with identifying critical paths, failure modes of business flows that routinely span micro-service chains. However, In a dynamic environment as this, it is difficult to keep up with dependencies. This talk is about a system we built at Flipkart that uses network connections between VMs to drive application intelligence that allows us to keep track of dependencies, and has several other potential applications.
