We prove that a selection of quality of information optimisation problems related to event detection in sensor networks are NP-hard.

Unbounded data structures, advanced functions and data types, and/or different forms of communication are often needed to model large and complex probabilistic real-time systems such as wireless sensor network algorithms. ...

Several formal models combine probabilistic and nondeterministic features. To allow their probabilistic simulation and statistical model checking by means of pseudo-random number sampling, all sources of nondeterminism ...

Distributed and concurrent object-oriented systems are difficult to analyze due to the complexity of their concurrency, communication, and synchronization mechanisms. The future mechanism extends the traditional method ...

Publish/subscribe (pub/sub) is a popular communication paradigm in the design of largescale distributed systems. A fundamental challenge in deploying pub/sub systems on a data center or a cloud infrastructure is efficient ...

Congestion occurs at a bottleneck along an Internet path; multiple flows between the same sender and receiver pairs can benefit from using only a single congestion control instance when they share the same bottleneck. These ...

PSMaude is a probabilistic extension of Maude that provides an expressive probabilistic strategy language to quantify the nondeterminism in probabilistic rewrite theories, allowing the user to specify different probabilistic ...
