Spatio-temporal information is essential for specifying and verifying Internet of Vehicles (IoV). Multi-lane spatial logic (MLSL) is a real-time spatial logic that can specify constraints in traffic manoeuvres on multi-lane motorways. It turns out to be a promising way to specify the properties of traffic manoeuvres because of its domain specificity and simplicity in modeling and reasoning. In this...
The service mashup programming paradigm is a blooming faction of service oriented Architecture for developing web applications. A mashup application constructs its functionality by combining data, presentation and functionalities obtained from online services published by service providers such as Google and Amazon. This paradigm significantly facilitates the implementation of application and reduces...
Mobile Ad hoc Networks (MANETs) are networks dynamically formed by mobile nodes without the support of prior stationary infrastructures. The essential features of such a network are local broadcast, mobility and probability. In our earlier work, we proposed the pw-calculus to formally model and reason about MANTEs from a group probabilistic perspective, in which a MANET node can locally broadcast...
Competitions of shared web resources have been widely concerned today. Under the circumstances of networks, especially in distributed systems, central supervisor can hardly be implemented, which makes it more complicated to prevent deadlock problems. This paper describes the competitions of web services for shared web resources using CSP method. Deadlocks can be analyzed based on the formal model...
As a programming model, MapReduce is implied for easier processing and generating large cluster of distributed data sets. We use CSP framework to model MapReduce system through which the parallelization of the computation and the distribution of data across multiple machines can be reflected. Some properties of MapReduce can be verified based on the achieved model.
