The paper explores the conditions that determine the effect of rule enforcement policies that imply an attempt to punish all the visible violations of the rule. We start with a simple game-theoretic analysis that highlights the value of gentle COntinuous Punishment (gentle COP) policies. If the subjects of the rule are rational, gentle COP can eliminate violations even when the rule enforcer ha...

The system adaptability is one of the most important capabilities required for a next generation open system. Many research efforts have developed adaptable systems that allow various applications to meet their specific requirements by combining different policies. However, the policy coordination is still problematic. Fine-grained policies are sometimes not orthogonal, but often have complex c...

High-performance computing is rapidly expanding to include distributed collections of heterogeneous sequential and parallel systems and irregular applications with complex, data dependent execution behavior and time varying resource demands. To provide adaptive resource management for dynamic applications, we are developing the Autopilot toolkit. Autopilot provides a exible set of performance s...

Service provisioning has gained significant attention as a promising programming model for heterogeneous wireless sensor networks. Its key idea is to exploit the decoupling of service providers and consumers to enable platform-independent applications that are dynamically bound to platform-specific services. We explore novel adaptive service binding strategies that are able to cope with network...

Throughput maximization of an adaptive transmission system with a finite number of transmitted power levels and code rates for communication over slow fading channels is analyzed based on the concept of information outage. Properties of throughput maximizing policies lead to an iterative algorithm that yields good system designs. Numerical results show that carefully designed discrete adaptive ...

Policies have traditionally been a way to specify properties of a system. In this paper, we show how policies can be applied to Organization-based Multiagent Systems Engineering (O-MaSE) [1], specifically in the Organization Model for Adaptive Computational Systems (OMACS) [2]. In OMACS, policies may constrain assignments of agents to roles, the structure of the goal model for the organization,...
