There is provided a system and method for resilient routing based on a multi-channel model for emergency management. The system includes a packet delivery anomaly detector for determining an existence of an anomaly in a mandated routing infrastructure for a packet that renders the packet incapable of reaching a destination node designated for the packet through the mandated routing infrastructure. The system further includes a dynamic alternate route identifier for dynamically identifying alternate routes for the packet responsive to a determination of the existence of the anomaly. The alternate routes are outside the mandated routing infrastructure, are provided using one or more mobile devices external to and not part of the mandated routing infrastructure, and are dynamically identified responsive to at least geographic location information. The system also includes a wireless transmitter for wirelessly routing the packet using at least one of the alternate routes.

1. Technical Field
The present principles relate generally to information routing and, in particular, to resilient routing based on a multi-channel model for emergency management.
2. Description of the Related Art
The disclosure will provide details in the following description of preferred embodiments with reference to the following figures wherein:
FIG. 1 shows an exemplary processing system 100 to which the present principles may be applied, in accordance with an embodiment of the present principles;
FIG. 2 shows an exemplary system 200 for resilient routing based on a multi-channel model for emergency management, in accordance with an embodiment of the present principles;
The present principles are directed to resilient routing based on a multi-channel model for emergency management.
In an embodiment, the present principles combine geographic location information with the capability of leveraging nodes not normally belonging to the routing network.
In an embodiment, we introduce the capability of exploiting different transmission and opportunistic media in order to deliver data to a targeted area, when the standard communication channels used for networking are segmented and the target destination is not directly available. Even though, the identification of alternative paths to a destination is a normal behavior of routing algorithms, the present principles differ from such approaches is the use of different media, such as portable devices (e.g., cellular phone), which act as a bridge towards the location that is isolated. These portable devices are used in an opportunistic manner and do not normally belong to the set of nodes that are used to route packets. Moreover, this approach can be complemented with GPS information about the destination of packets, which help the portable devices to smartly join the routing algorithm, based on their location and the intended destination of the packet to be transmitted. In an embodiment, we exploit the opportunistic use of mobile devices and their location in order to provide alternate routes when the standard routing nodes are not reachable because of segmentation of the network.
