Abstract:
1. A method of tracking content in networks having transient network communities where a collection of nodes making up the network may change over time, comprising steps of: using a persistent node identifier to uniquely identify each node in the network, even tough a different network address may be assigned to the node upon entering the network multiple times; creating a mapping between the persistent node identifier of each node and a current network address used by that node and revising the mapping to reflect the current network address assigned to the node upon subsequent entry of the node into the network, such that an identity of each of the nodes can be resolved even though a current network address assigned to the node upon entering the network may vary from one entry to another; for each of the nodes in the network, storing, at the node, a directed graph associated with each content resource currently available from that node, thereby enabling a network traversal path taken by each of the content resources to be known, wherein: maintaining the complete network traversal path upon each transmission of each of the content resources, further comprising steps of:
