Indian Institute of Technology Hyderabad (IITH) is a premier institute of science and technology established in 2008. IITH has been consistently ranked in the&nbsp;<a href="https://iith.ac.in/reports/" rel="noopener noreferrer">top 10 institutes</a>&nbsp;in India for Engineering&nbsp;<a href="https://www.nirfindia.org/2021/EngineeringRanking.html" rel="noopener noreferrer" target="_blank">according to NIRF</a>&nbsp;making it one of the most coveted schools for science and technology in the country.

IITH offers&nbsp;<a href="https://iith.ac.in/academics/under-graduate/">undergraduate programs</a>&nbsp;in all the classical engineering disciplines, applied sciences, design, as well as several modern interdisciplinary areas. Students are given a flexibility to explore a broad set of areas, and potentially pursue a minor or double major in a discipline that is not their own. Students who wish to seek a deeper understanding of their own discipline are strongly encouraged to get involved in cutting-edge research with the help of a faculty to mentor them, and earn an Honors in their own field.

The very foundation of IIT Hyderabad is based on&nbsp;<a href="https://iith.ac.in/research/">research and innovation</a>. The vibrant research culture is evident from the number of patents and publications that IITH produces consistently every year. IITH offers&nbsp;<a href="https://iith.ac.in/academics/programmes-offered/">graduate programs</a>&nbsp;at both a masters, and a doctoral level, in several diverse areas. There are separate programs for technology, design, science, and liberal arts. The&nbsp;<a href="https://iith.ac.in/academics/post-graduate/">MTech program</a>&nbsp;is offered in various modes and durations to cater to the ever-growing need of postgraduate level professionals in the country.

IITH encourages and supports&nbsp;<a href="https://iic-iith.netlify.app/index.html" rel="noopener noreferrer" target="_blank">innovation and entrepreneurship</a>&nbsp;at every stage. The minor program in entrepreneurship is open to all students of IITH, and many of the courses are offered by industrialists who are entrepreneurs themselves. There are various&nbsp;<a href="https://iith.ac.in/research/centres-incubators/">innovation centers and incubators</a>&nbsp;that promote entrepreneurship and help mentor young innovators. IITH has been very successful in building tie-ups with leading academic institutions around the globe.

IITH enjoys a very special relationship with Japanese universities and industries that goes beyond academic and research collaborations. In fact, some of the iconic buildings in IITH campus will carry the signature of Japanese architecture.

IITH creates a unique holistic ecosystem for education that offers interactive learning, a very flexible academic structure, cutting-edge research, strong industry collaboration, and entrepreneurship. This is an environment which enables students and faculty to translate their dreams into realities.

Distributed Hash Tables (DHTs) and Random Peer Sampling (RPS) provide important and complementary services in the area of P2P overlay networks. DHTs achieve efficient lookup while RPS enables nodes to build and maintain connectivity in the presence of high churn. Clearly, many applications, e.g. in the area of search, would greatly benefit if both these services were available together at a reasonable cost. This paper integrates a structured P2P overlay and a Random Peer Sampling service through gossip protocols. This system called D2HT, leverages the small-world nature of DHTs and relies on two cohabiting gossip protocols maintaining the close and long-range links respectively. The long links are chosen according to a harmonic distribution, following the Kleinberg small-world model. This approach exhibits several benefits: (i) The resulting DHT is highly dynamic and selfstabilizing, changes are tracked for free through the gossip nature of the protocol. This removes the need for complex, usually disjoint, and expensive join and repair procedures. Yet, it achieves reasonable routing performance with respect to standard DHTs; (ii) The resulting peer sampling service provides a biased sampling following a harmonic distribution: this improves the routing without jeopardizing the quality of the RPS. The set of long-range links which are a source of RPS can be used independently by others applications for free. They change continuously, achieving well-balanced routing across the nodes. We perform extensive simulations and compare the performances of D2HT with Cyclon, HRing, Symphony and Pastry to demonstrate the gains achieved by the approach proposed in this paper. © 2010 IEEE.
