Networks of embedded smart cameras are an emerging technology for a broad range of pervasive computing applications including smart rooms, intelligent infrastructures and security. Smart cameras combine video sensing, processing and communication within a single embedded device and provide sufficient onboard infrastructure to perform high-level video analysis tasks. This paper deals with middleware services required for the efficient deployment and operation of distributed smart cameras. We focus here on services for autonomous and dynamic reconfiguration. Dynamic reconfiguration refers to the exchange of software tasks as well as the alteration of QoS-levels these tasks provide during runtime. Dynamic reconfiguration provides several advantages over statically configured networks including (i) modification of functionality after deployment and during runtime, (ii) adaptation of the network to changes in its internal and external state, and (iii) better exploitation of the available resources. We have developed the services for dynamic reconfiguration using policies. Policies help to specify rules for the reconfiguration process. By evaluation the policy the new task-level configuration of the network is computed. The reconfiguration is implemented using mobile agents in order to achieve a flexible and scalable middleware service. Our policy-based middleware is demonstrated by a surveillance application.

DRAMA 1 is a distributed policy-based management system designed to manage Mobile Ad hoc NETworks (MANETs). Its design philosophy is to create intelligent, self-adaptive policy agents to manage dynamic networks without human intervention. Network management functions are performed in a distributed fashion by these policy agents, rather than being controlled by a centralized management station. Policies are used to control the frequency and content of network management messages exchanged among policy agents in a way that reduces bandwidth usage and increases the utility of management messages. This greatly enhances management efficiency and reduces the bandwidth overhead required for network management. As with any new technology, there is a question about the scalability of this approach. The purpose of the work described in this paper is to study whether the DRAMA policy-based network management system can scale to networks of 500+ nodes. The study uses a novel simulation-based approach to evaluate DRAMA performance when DRAMA is used to manage MANETs of up to 500 nodes. The results confirm that the DRAMA distributed policy-based management paradigm provides superior performance over a centralized management paradigm for MANETs.

“…A policy can be eventually purged from the policy repositories and stored for historical reference purposes after it is deleted, which can happen when the policy will no longer be used. The Policy Agent Framework (PAF), as shown in Figure 2, features the integration of policy control with the agent component architecture [3]. The design of this policy agent framework has been transitioned to the U.S. Army FCS program as the building foundation for its network management system.…”

“…To address these needs, the U.S. Army CERDEC launched the DRAMA 1 (Dynamic ReAddressing and Management for the Army) Science and Technologies Objective (STO) to develop a tool suitable for managing MANETs. It resulted in the creation of a network management tool [2] [3][4] that is distributed, agent-based, and policy-enabled in order to provide the necessary self-healing and self-adaptive functionalities required for managing MANETs. The enforcement of policies by distributed intelligent agents allows the behavior of this management tool to autonomously adapt to dynamic network condition changes.…”

Towards Automation of Management and Planning for Future Military Tactical Networks

Mobile Ad hoc NETworks (MANETs) have been adopted as the building blocks of future military tactical networks. We believe that the dynamic nature of such networks makes the automation of both network management and network planning a necessity rather than just a desirable feature. The creation of DRAMA, a policy-based network management system designed for managing dynamic MANETs, is the first step of this automation effort. Since the current practice requires that policies be specified manually, which we have found to be a challenging task, it is highly desirable to automate the generation of network management policies by network planning. In this paper, we present our vision of automating the management and planning of future tactical networks, describe what has been accomplished and ongoing activities, and discuss future work towards achieving this vision.
