Failure detection (FD) is an important issue for supporting dependability in distributed
healthcare systems to guarantee continuous, safe, secure, and dependable operation, and …

Cloud computing is an increasingly important solution for providing services deployed in
dynamically scalable cloud networks. Services in the cloud computing networks may be …

Cloud Services are highly scalable and dynamic. Providing high availability and low latency
with high data rate is a big challenging task for service providers. Any deviation in the …

Real-time activity recognition is an important research problem, which has drawn the
attention of many researchers for many years. All previous works of real-time activity …

Unreliable failure detectors have been an important abstraction to build dependable
distributed applications over asynchronous distributed systems subject to faults. Their …

Delays are inevitable in complex distributed environments. Timeout mechanisms are
commonly used to handle unexpected failures in distributed systems. However, incorrect …

In this paper, we analyze the performance of consensus protocols based on the rotating
coordinator paradigm. We consider a simulated production environment, on which …

Chandra and Toueg first investigated the problem of solving consensus in asynchronous
systems with unreliable failure detectors. In practice, such failure detectors work by …

Due to their fundamental role in the design of faulttolerant distributed systems, consensus
protocols have been widely studied. Most of the research in this area has focused on …

This paper compares several parametric and adaptive failure detection schemes in terms of
their respective QoS. We introduce an improvement over existing methods, and evaluate …
