Chuan Duan, Jane Cleland-Huang, Bamshad Mobasher
2008 Proceeding of the 17th ACM conference on Information and knowledge mining - CIKM '08  
In this paper, we propose a semisupervised clustering framework, based on a combination of consensus-based and constrained clustering techniques, which can effectively handle these challenges.  ...  Specifically, we provide a probabilistic analysis for informative constraint generation based on a co-association matrix, and utilize consensus clustering to combine multiple constrained partitions in  ...  A CONSENSUS BASED CONSTRAINED CLUSTERING FRAMEWORK To address the problem of generating more informative constraints and improving the quality of constrained clustering especially for software requirements  ...

Energy Efficient Consensus Approach of Blockchain for IoT Networks with Edge Computing

Shivani Wadhwa, Shalli Rani, Kavita Kavita, Sahil Verma, Jana Shafi, Marcin Wozniak
2022 Sensors  
This paper proposes the consensus approach on the basis of PoW, where a single miner is selected for mining the task. The mining task is offloaded to the edge networking.  ...  In the past few years, many consensus algorithms, such as proof of work (PoW), ripple, proof of stake (PoS), practical byzantine fault tolerance (PBFT), etc., have been designed to improve the performance  ...  Acknowledgments: Jana Shafi would like to thank the Deanship of Scientific Research, Prince Sattam bin Abdul Aziz University, for supporting this work.  ...

Over-the-Air Updates for Robotic Swarms

Vivek Shankar Varadharajan, David St Onge, Christian GuB, Giovanni Beltrame
2018 IEEE Software  
Common practices A common method to update the software of a group of robots relies on a connection to a central node transmitting the changes to each robot within range.  ...  The protocols to transmit, encrypt and test the updates are well-studied [3], but this approach comes with critical disadvantages:1. it requires a pre-deployed network infrastructure like a router mediated  ...  To achieve consensus in a distributed network, our approach borrows concepts from swarm intelligence [7] . It reaches an agreement on the code version using a gossip-based algorithm [8] .  ...
