Topic:

Consensus protocols for IoT systems with blockchains

This work proposes Practical Byzantine Fault Tolerance (PBFT) ordering service needed for block formation in permissioned blockchain environments. Contrary to current PBFT implementations that only provide a single point of entry to the ordering service, we allow each ordering node to act as an entry point that proposes and conducts the consensus process of including new record in the distributed ledger. To ensure atomicity of record insertion in distributed ledger, we have developed a bandwidth reservation protocol that uses a modification of CSMA/CA protocol to regulate access to the broadcast medium formed by the P2P network of TCP connections between orderers. Further we address proof of stake (PoS) and delegated proof of stake consensus protocols integrated with PBFT. We also address cluster interconnections which can increase coverage of PBFT system.

Topic:

A Deep Unsupervised Learning Framework for Constrained Radio Resource Management Problems

The next generation of wireless networks is anticipated to be more complex and heterogeneous due to higher transmission frequencies, massive antenna deployments, and ultra-dense access points. Subsequently, the application of traditional optimization-based radio resource management (RRM) solutions is becoming difficult as they are typically non-scalable and computationally exhaustive. In this context, deep unsupervised learning is emerging as a potential solution to enable online implementation of RRM solutions without high-quality training labels and much reduced time complexity.  Nevertheless, incorporating and satisfying various constraints with zero violation in a deep unsupervised learning architecture is a fundamental challenge.   Therefore, this talk will discuss two novel differentiable projection-based approaches and their application to solve the classical power control problem in the presence of minimum data rate constraints. The first approach utilizes a differentiable convex optimization layer to implicitly define a projection function, whereas the other approach uses an iterative differentiable correction process. To enhance the sum-rate performance of the proposed models even further, the application of Frank-Wolfe algorithm (FW) will be shown. Our results depict that the proposed solutions not only improve the achievable data rate but also achieve zero constraint violation probability, compared to the existing approaches. Also, the proposed solutions outperform the classic optimization methods in terms of computation time complexity.
