Virtual Backbone Content Routing in Wireless Ad-Hoc Network

The authors developed a new content routing based on the virtual backbone structure, which groups wireless nodes and contents into a virtual architecture. The approach is scalable, works with local information, and does not rely on address information. The naming system uses flat naming to identify nodes and contents, and organizes these identifiers together. Backbone nodes can be selected automatically or predefined to direct their associated normal nodes in a local area. The normal nodes are guided by the backbone nodes to fulfill the searching and routing processes. With a virtual structure, the searching performance can be improved by using the DHT technique.
