Using higher-order contracts to model session types

Giovanni Bernardi ; Matthew Hennessy.

Session types are used to describe and structure interactions between independent processes in distributed systems. Higher-order types are needed in order to properly structure delegation of responsibility between processes. In this paper we show that higher-order web-service contracts can be used&nbsp;[&hellip;]

Compositional Reasoning for Explicit Resource Management in Channel-Based Concurrency

Adrian Francalanza ; Edsko DeVries ; Matthew Hennessy.

We define a pi-calculus variant with a costed semantics where channels are treated as resources that must explicitly be allocated before they are used and can be deallocated when no longer required. We use a substructural type system tracking permission transfer to construct coinductive proof&nbsp;[&hellip;]

Modelling Probabilistic Wireless Networks

Andrea Cerone ; Matthew Hennessy.

We propose a process calculus to model high level wireless systems, where the topology of a network is described by a digraph. The calculus enjoys features which are proper of wireless networks, namely broadcast communication and probabilistic behaviour. We first focus on the problem of composing&nbsp;[&hellip;]

A calculus for costed computations

matthew hennessy.

We develop a version of the pi-calculus, picost, where channels are interpreted as resources which have costs associated with them. Code runs under the financial responsibility of owners; they must pay to use resources, but may profit by providing them. We provide a proof methodology for processes&nbsp;[&hellip;]
