How to fast index and retrieve the photos is one key issue in photo management. In this paper, we present a semantic-based graph index for finding the relevant photos from one photo. First, we cluster photos into many different collections by single-dimension context like time, location, author and tag and form initial single-context photo clustering graphs. Second, we analyze the semantic relation of the context by semantic correlation to form single-context semantic relation graph. Third, we fuse the initial single-context photo clustering relation graph and single-context semantic relation graph into single-context photo semantic relation graph. Lastly, we combine the all single-context photo semantic relation graphs into a multi-dimensional photo semantic relation graph as indexing graph. The graph index method has been implemented in Kaleido Photo which is a photo-centric management system and test results show the method is efficient for photo indexing and retrieval.

It is a reservation mechanism that inherits the advantages of RSVP but is a lightweight version of RSVP. DPRP transports and negotiates the QoS requirement between sources and destinations as well as reserves PHB for service levels in each DS domain. It negotiates a dynamic service level agreement (SLA) between various domains efficiently and guarantees the end-to-end QoS of the DiffServ network. Essential principles and advantages of DPRP are presented

Those two algorithms have complementary advantages. In this paper, we propose a new scheme called previous network subscription, which can provide low handover delay for real time multicast applications. We also propose a new multicast routing protocol called RHMoM (Region based Hierarchical Mobile Multicast) by combining the previous network subscription and the home subscription. RHMoM uses two kinds of agent and employs the region based hierarchical architecture to limit the reconstruction frequency of the multicast tree and optimize the delivery path. The simulation results show that RHMoM has better performance than other mobile multicast solutions in mobile IPv6 network.
