Abstract
Methods and systems for information dissemination in mobile ad hoc networks founded on Content Based Routing. The method comprises encoding, via an encoding logic within the source node, a plurality of information categories associated with the content in a header of the packet, encrypting the packet with an encryption key unique to the plurality of information categories, with the encrypted packet having a unique dissemination group identity in its header, and disseminating the encrypted packet to nodes that have subscribed to the data based on the dissemination group identity. The system comprises a host within the source node, an identity generator to generate the dissemination group identity for the content, an encryption unit for encrypting the content, and a routing unit to disseminate the content to the dissemination mesh based on established subscriptions.
