In this paper we develop a copula based approximation framework for scalable analysis of Stochastic Automata Networks (SAN) arising in reliability analysis, and can be described by CTMCs. Copulas provide a general approach to model joint distributions in terms of their marginals. Using copulas functions, the dependencies between the interacting automata in the SAN can be captured in terms of local...
Hybrid systems are a useful abstraction for systems that have a combination of discrete and continuous dynamics. For typical examples of hybrid systems, there can be various sources of stochasticity. The source of stochasticity can be in the dynamics of the continuous states, the probabilistic switching between various modes of the system and the probabilistic resetting of the continuous state after...
The problem of maximizing the sum of the transmit rates while limiting the outage probability below an appropriate threshold is investigated for networks where the nodes have limited processing capabilities. We focus on CDMA wireless network whose rates are characterized under mixed Rayleigh- lognormal fading. The outage probability is given implicitly by a complex function so that solving the optimization...
