In secret sharing schemes, there is always a special participant called the dealer who controls the distribution of the secret S. It is so powerful that once the dealer is depraved, the whole system is to be paralyzed. In order to solve this problem, it is necessary to cancel the privilege of the dealer and realize completely fair secret sharing. In this paper, we make use of the excellent additivity...
The paper is mainly about positioning and navigation of mobile terminal, and provides a solution of the combination of A-GPS and LF (Location Fingerprint) technology. The solution takes advantages of GPS positioning and CELL-ID positioning, which keep the accuracy and convenience of current technologies and promote coverage for users. Also, energy saving is in detail discussed. By the prediction of...
Address dynamic configuration in the IP-based network is often accomplished by the dynamic host configuration protocol (DHCP), however, the mobility of mobile ad hoc network (MANET) nodes always involve unpredictable topology changes. Previous works on IP address in ad hoc network assumes that all the address is configured statically by the centralized administration. However, as with the rapid development...
In this paper, we intended to seek a method to retrieval media files on personal mobile devices efficiently. We aimed at finding media-generated event accurately to provide support for annotation and retrieval of multimedia files. In this paper, the event-cluster positioning is realized by spatio-temporal clustering. Time clustering uses a method that maps the time difference to image, and then finds...
This paper focuses on the issue of flow distribution for multimode mobile terminals in heterogeneous networks, and proposes a flow distribution algorithm based on priority and weight self-production mechanism. The algorithm utilizes the notion of "priority" , assigning higher priorities to more important sessions, therefore ensuring these sessions have the preferential utilization of the...
In MIPv6, the home agent (HA) is the key entity to ensure a mobile nodepsilas (MN) reachability. A single HA on the home link will become a performance bottleneck. In order to enhance service availability and improve system performance, it is necessary to configure multiple HAs on the home link and efficiently balance load among these HAs. This paper proposes a dynamic multiple HA load balancing mechanism...
This paper proposes a new cross layer scheme (fast RSVP) to reserve resources for mobile IPv6. Through the cooperation of mobile IP and RSVP modules, fast RSVP includes a number of mechanisms such as advance resource reservation on neighbor tunnels, resource reservation on optimized routes, resource reservation for handover sessions (guard channel) etc. Network simulation results show that our scheme,...
