Attack resistant Leader Election in Social Overlay Networks by Leveraging Local Voting

Current leader election algorithms fail in the presence of Sybil attacks, i.e., one malicious entity inserting many nodes, network dynamics, and restricted knowledge about the graph. However, social overlay networks, i.e., peer-to-peer networks with links corresponding to social relationships, face all of the above challenges. Social overlay...

An Incremental VON-Based Debug System for Commercial FPGA Architecture

Electronic companies are increasingly using field-programmable gate arrays in various domains such as application acceleration, complex digital designs or ASIC prototyping. The Verification phase holds a significant place in the FPGA design development process. A key challenge during verification is observability. This is defined as the ability...

Multi-level Reconfigurable Self-organization in Overlay Services

Large-scale decentralized systems organized in overlay networks are complex to manage. Such systems integrate organizational complexity in the application-level resulting in low abstraction and modularity in their services. This thesis introduces a multi-level conceptual architecture for overlay services. An overlay service is a large-scale...
