Yale and Tata Group form research alliance

Yale University and the Tata group have launched a far-ranging research collaboration that builds on their shared strengths in discovery, technology, and innovation. The alliance will be led at Yale by Nicholas Christakis ’84, co-director of the Yale Institute for Network Science (YINS) and the Sol Goldman Family Professor of Social and Natural Science.

YINS Seminar: Sekhar Tatikonda & Patrick Rebeschini

“Locality in Network Optimization”

Speaker: Sekhar Tatikonda
Associate Professor of Electrical Engineering
Yale University

Talk Summary: The complexity of network optimization depends on the network topology, the nature of the objective function, and what information (local or global) is available to the decision makers.   In this talk we introduce a notion of network locality and explore some of its properties.  (Joint work with Patrick Rebeschini.)

Tassiulas receives ACM Mobihoc 2016 Best Paper Award

Leandros Tassiulas received the ACM Mobihoc 2016 Best Paper Award, for the paper “Throughput-optimal Broadcast in Wireless Networks with Dynamic Topology” co-authored with collaborators Abhishek Sinha and Eytan Modiano from MIT. Mobihoc is the ACM International Symposium on Mobile AdHoc Networking and Computing, one of the premier forums for wireless networking.

Broadcasting is one of the primary information transport modes in a network, where a piece of information needs to be communicated to each and every participant node. It is a key constituent in a lot of today’s  applications that deal with the collection, processing and dissemination of massive amounts of data. In a mobile wireless network where the nodes frequently get disconnected, it becomes fairly challenging to ensure broadcast delivery.  Either multiple, possibly redundant transmissions are needed or atedious bookkeeping  of who heard what and in what precedence. In this paper the authors provide a broadcasting methodology and an algorithm that ensures message delivery in the challenging wireless mobile environment, while at the same time the supported rates of information delivery are maximized. Furthermore they characterize the achieved network capacity.
