description The invention provides a content request forwarding method based on hybrid mobile content center network. According to the method, a mobile requesting node generates a content request data packet and determines whether there is a neighboring node in the communication radius. If there exists such a node, the content request data packet is sent to the neighboring node; otherwise, the content request packet is forwarded to a clustering head node. If there is a request content in the cache of the neighboring node, the neighboring node forwards the content directly to the requesting node; otherwise, the content request packet is forwarded to the clustering head node by the neighboring node furthest away from the requesting node. If the cache of the clustering head node contains the request content, the content is forwarded to the requesting node through the original path; otherwise, the request content is forwarded through a base station to the requesting node via the original path. The method of the invention can
