An Intelligent, dynamic, long-term digital Surveillance Media storage System (ISMS), proposes an intelligent, dynamic, digital media storage mechanism for digital surveillance applications that can analyze media streams in real-time and provide flexible, scalable, and self-adjustable encoding and indexing mechanisms based on actual needs for digital surveillance systems. The system includes several subsystems, such as: (1) a media stream retriever/receiver; (2) a content-based description generator; (3) an intelligent engine with metadata description storage and media file storage (4) an event manager; (5) a media stream writer; and (6) an encoding optimizer.

The originator requests information from a target by launching a receptor agent that propagates across the mobile ad hoc network to the target. Along the way, intermediate nodes retain copies of the receptor. The target adds reply information to the receptor and launches it onto the network. When the reply-bearing receptor rendezvous with a receptor copies that contain matching patterns corresponding to the reply-bearing receptor, the reply information is transferred to those receptor copies. The information transferred may be encrypted at the target, using encryption key supplied by the originator. In this way, intermediate nodes cannot access the information being propagated in the receptors that they host.
