Access Control for Distributed Ledgers in the Internet of Things: A Networking Approach [article]

Andrew Cullen, Pietro Ferraro, William Sanders, Luigi Vigneri, Robert Shorten
2021 arXiv   pre-print
However, without PoW, implementation of these DLTs requires an access control algorithm to manage the rate at which nodes can add new transactions to the ledger.  ...  In this work, we consider a class of IoT-friendly DLTs based on directed acyclic graphs, rather than a blockchain, and with a reputation system in the place of Proof of Work (PoW).  ...  An access control algorithm satisfies the fairness in dissemination rate requirement if allocation of dissemination rate among nodes is max-min fair, weighted by each node's reputation.  ...

2007 Parallel Architecture and Compilation Techniques (PACT), Proceedings of the International Conference on  
Technology trends are leading to increasing number of cores on chip. All these cores inherently share the DRAM bandwidth.  ...  The on-chip cache resources are limited and in many situations, cannot hold the working set of the threads running on all these cores. This situation makes DRAM bandwidth a critical shared resource.  ...  Acknowledgments The authors would like to thank Asad Khan Awan for discussions on network fair queuing. We would also like to thank anonymous reviewers for their feedback.  ...

Measurement-based opportunistic scheduling for heterogenous wireless systems

S. Patil, G. De Veciana
2009 IEEE Transactions on Communications  
In other words the penalty associated with tuning weights for other schemes can be higher than that associated with estimating users' rate distributions for maximum quantile scheduling.  ...  Furthermore we prove that if rates are bounded and number of users is high, maximum quantile scheduling is sum average throughput maximizing subject to temporal fairness.  ...  However in practice the weights for each user needs to be estimated, we investigate the sensitivity of system throughput to errors in these weights by performing two controlled experiments.  ...
