“…Several policy-based systems exist where policies are used to achieve different purposes. In [6], the authors present a policy-based management framework for ambient networks to allow the interoperation of different and heterogeneous networks. Even though several policy specification languages exist, depending on the type of application where the policies are to be used, new designs impose themselves.…”

Security is becoming one of the major issues that mobile users face. With their powerful devices, they are willing to take advantage of the wide range of services provided in mobile environments. Therefore, in this paper, we propose a solution to provide mobile users and service providers with security at different levels. Indeed, software policies enable each user/ service provider to specify the rules for what they consider safe transactions. We also show that the addition of context information enhances security.

Autonomic network management is a vision that brings autonomic computing principles to network management. In this vision, the use of policies is a key aspect. Besides, it is necessary to add some level of decentralization to enable broad autonomic capabilities. Thus, the elements that build decentralized autonomic network management systems (known as autonomic management elements) must be policy-enabled. However, the consistency of policy states among autonomic management elements is an important challenge. Traditional mechanisms to maintain consistency of these states are supported by some centralization which wastes some desirable properties of decentralization. In contrast to these mechanisms, we propose a distributed, scalable and robust mechanism to maintain the consistency of policy states. In this paper we introduce multiagent truth maintenance features in decentralized autonomic network management as a mechanism to bring consistency maintenance of policy states. We developed a model of a decentralized autonomic network management system on Peersim to perform simulation experiments. Besides, the utilization of policies in P2Pbased autonomic network management systems is presented as case study.

Complex Dynamic Networks can be exploited in solving problems where traditional solutions may not be sufficient. The increasing complexity of computer networks imposes problems to the current network management solutions. In this context, network management is an example of a research area that could benefit from the use of CDNs. However, the consistency of state of management data among the elements that build management CDNs (management nodes) is an important challenge. Traditional mechanisms to maintain consistency of these states are supported by some centralization which wastes some desirable properties of CDNs (e.g., robustness). In contrast to these mechanisms, we propose a distributed, scalable and robust mechanism to maintain the consistency of state of management data in management CDNs. Our mechanism introduces multi-agent truth maintenance features and communication strategies based on dynamic process to provide consistency maintenance of state of management data. We developed a model of a management CDN on Peersim simulator to perform experiments. Besides, 2 case studies are presented. The result obtained supports our scalability and robustness claims.
