PFMA: Policy-Based Feedback Management Architecture for Wireless Sensor Networks

Wireless sensor networks are usually designed in an ad hoc manner and often consider some simple management methods. As the sensor networks become more and more complex, it will be difficult to maintain the normal network operations and the completion of user's task will not be guaranteed efficiently if there are no effective management methods. Wireless sensor network is an application-specific system, so its management not only includes traditional network management functions, but has risen to the level of system management. In this paper, we use policy-based management to integrate system management and network management and propose an integrated sensor network management architecture PFMA (policy-based feedback management architecture). The overall performance of sensor networks has been effectively improved through PFMA.
