Ad hoc networking is the basis of the future military network-centric warfare architecture. Such networks are highly dynamic in nature, as mobile ad hoc networks are formed over wireless links that are susceptible to failure. Strict requirements on security and reliability combined with the dynamic nature of the network provide a strong motivation for self-forming, self-configuring, and self-healing capabilities in the network. This paper describes a policy-based mobile ad hoc network management system that addresses these needs. The system provides the capability to express networking requirements in the form of policies at a high level and have them automatically realized in the network by intelligent agents. Our system provides the following capabilities: flexible monitoring and reporting that enables collection of management information from network elements at configurable intervals; automated configuration and reconfiguration of network elements based on reported network status; user-definable aggregation and filtering of monitored management information at the source of the data so as to reduce management station processing and network transmission overhead.
