%D 2006 %L eprints296 %X Klaim is an experimental language designed for modeling and programming distributed systems composed of mobile components where distribution awareness and dynamic system architecture configuration are key issues. StocKlaim [R. De Nicola, D. Latella, and M. Massink. Formal modeling and quantitative analysis of KLAIM-based mobile systems. In ACM Symposium on Applied Computing (SAC). ACM Press, 2005. Also available as Technical Report 2004-TR-25; CNR/ISTI, 2004] is a Markovian extension of the core subset of Klaim which includes process distribution, process mobility, asynchronous communication, and site creation. In this paper, MoSL, a temporal logic for StocKlaim is proposed which addresses and integrates the issues of distribution awareness and mobility and those concerning stochastic behaviour of systems. The satisfiability relation is formally defined over labelled Markov chains. A large fragment of the proposed logic can be translated to action-based CSL for which efficient model-checkers exist. This way, such model-checkers can be used for the verification of StocKlaim models against MoSL properties. An example application is provided in the present paper. %A Rocco De Nicola %A Pieter Katoen %A Diego Latella %A Mieke Massink %J Electronic Notes in Theoretical Computer Science %N 2 %R 10.1016/j.entcs.2005.10.037 %P 161-175 %T Towards a logic for performance and mobility %V 153 %I Elsevier %O Proceedings of the Third Workshop on Quantitative Aspects of Programming Languages (QAPL 2005)
