This paper studies the problem of realizing a common software clock among a large set of nodes without an external time reference (i.e., internal clock synchronization), any centralized control, and where nodes can join and leave the distributed system at their will. The paper proposes an internal clock synchronization algorithm which combines the gossip-based paradigm with a nature-inspired approach,...
This paper proposes an internal clock synchronization algorithm for very large number of processes that is able to (i) self-synchronize their local clocks without any central control and (ii) resist to attacks of an adversary whose aim is to put out-of-synchronization as many correct processes as possible. To cope with scale the algorithm utilizes the gossip-based paradigm where each process has a...
Middleware for timely and reliable data dissemination is a fundamental building block of the event driven architecture (EDA), an ideal platform for developing air traffic control, defense systems, etc. Many of these middlewares are compliant to the data distribution service (DDS) specification and they have been traditionally designed to be deployed on managed environments where they show predictable...
