"Distributed Computing and Biological Systems"

The study of algorithms is traditionally motivated by an engineering and technological point of view. In recent years, several works have demonstrated that the understanding of biological phenomena can benefit from an algorithmic perspective. This approach may be particularly use- ful in the context of distributed computing. Indeed biological systems are distributed in nature (e.g., cells are composed of proteins, organs are composed of cells, populations are composed of organisms etc.), employing a combination of intertwined hierarchal and non-hierarchal coop- erative systems. The adaptation of ideas from theoretical distributed computing to biological systems is highly non-trivial and requires a delicate and careful treatment. In this talk, I shall discuss some of the recent works in this framework of research and point out several challenging directions for future work.

"On data insertion and migration in erasure-coding based large-scale storage systems"

 

Given the vast volume of data that needs to be stored reliably, many data-centers and large-scale file systems have started using erasure codes to achieve reliable storage while keeping the storage overhead low. This has invigorated the research on erasure codes tailor made to achieve different desirable storage system properties such as efficient redundancy replenishment mechanisms, resilience against data corruption, degraded reads, to name a few prominent ones. A problem that has mainly been overlooked until recently is that of how the storage system can be efficiently populated with erasure coded data to start with. In this talk, we will look into two distinct but related scenarios: (i) Data insertion - New data being inserted in the system directly in erasure coded format, (ii) Data migration- Existing replicated data being migrated to an erasure coded archive. We will elaborate on coding techniques to achieve efficient data insertion and migration, and in doing so, explore the connection of these techniques with recently proposed locally repairable codes such as self-repairing codes.

"Energy efficient distributed computation on mobile devices"

Energy consumption is a critical aspect of mobile applications. Excessive drain of battery is one of the key complaints of handheld device users and a success bottleneck for many mobile applications. In this talk I will look at energy-efficiency from the application development point of view. What are the key principles in energy consumption in cellular and WiFi communication? What kind of techniques can be used to reduce the energy consumption? Can cloud computing help? What can we expect in the future? I will use video streaming and peer-to-peer file sharing as examples.

"Participatory Sensing: Crowdsourcing Data from Mobile Smarphones in Urban Spaces"

The recent wave of sensor-rich, Internet-enabled, smart mobile devices has opened the door for a novel paradigm for monitoring the urban landscape known as participatory sensing. Using this paradigm, ordinary citizens can collect multi-modal data streams (e.g., audio, video, sound, location coordinates, etc) from the surrounding environment using their mobile devices and share the same using existing communication infrastructure (e.g., 3G service or WiFi access points). The data contributed from multiple participants can be combined to build a spatiotemporal view of the phenomenon of interest and also to extract important community statistics. Given the ubiquity of mobile phones and the high density of people in metropolitan areas, participatory sensing can achieve an unprecedented level of coverage in both space and time for observing events of interest in urban spaces. Several exciting participatory sensing applications have emerged in recent years. For example, GPS traces uploaded by drivers and passengers can be used to generate realtime traffic statistics. Similarly, street-level audio samples collected by pedestrians can be aggregated to create a citywide noise map. In this talk, we will provide a comprehensive overview of this new and exciting paradigm and outline the major research challenges.
