  • Publication number: 20140329497
    Abstract: This invention proposes novel systems, methods and apparatus that utilize smart devices (e.g., smartphones) capable of reading/processing biometric inputs, and wireless communications over secure, short-range wireless channels (e.g., near field communications (NFC)) to securely access websites and cyber-physical system (CPS) entities such as vehicles, rooms and control knobs as well as sensors and smart meters. A user accesses a website on a display terminal or CPS entity by using her smart device to send her biometric credentials to request access for a service, and communicates with either the said terminal or the said CPS entity which is also capable of short-range wireless communications, using secure and short-range wireless channels to ensure the authenticity of the user when using the service.

  • Patent number: 7701848
    Abstract: An efficient trap avoidance and shared protection method in a survivable network with shared risk link groups. The invention includes a fast and efficient heuristic algorithm for avoiding traps, an algorithm, which may also be applied effectively to shared SRLG protection. Compared to other existing algorithms, the algorithm embodied in the present invention runs much faster, and yet falls into few traps, and achieves a much higher bandwidth efficiency. This technology can be applied to MPLS, ATM, SONET, WDM, and other high-speed survivable network designs.

  • Patent number: 7444152
    Abstract: The present invention provides signaling protocols that enable an integrated cellular relaying system to support a call for a wireless terminal. In embodiments of the invention, the wireless terminal is redirected to a relaying path corresponding to at least one relaying station. A relaying station communicates with the wireless terminal and with other relaying stations. In addition, one of the relaying stations (that is configured in the relaying path) completes the relaying path by communicating with a base transceiver station.

  • Publication number: 20080240147
    Abstract: This invention proposes unique methods and apparatus for networking low cost low energy sensor nodes. The invention focuses on efficient Media Access Control (MAC) schemes to provide differentiated Quality of Service (QoS) to the sensor nodes in single-hop wireless and wired networks where the source nodes do not have a receiver module. Hence they can only transmit data to a sink but cannot receive any control signals, like an ACK or NAK, from any other node. None of the existing schemes like polling or scheduled transmissions, CSMA or ARQ is thus effective in this type of networks. The proposed scheme provides QoS to the nodes using distributed control by allowing them to transmit each packet an optimal number of times within a given interval.

  • Patent number: 7398321
    Abstract: This invention broadly comprises a novel segment protection scheme (survivability framework) for a network, which we refer to as PROMISE (Protection using MultIple SEgments). It combines the best of existing link and path protection schemes (e.g., bandwidth efficiency and fast recovery). The PROMISE approach divides an active path or AP (along which a survivable connection is established) into several, possibly overlapping active segments or ASs, and then protects each AS with a detour called backup segment or BS (instead of protecting the AP as a whole as in path protection schemes). This facilitates the bandwidth sharing not only among the BSs for different APs, but also among those for the same AP. In addition, recovery time can be shortened due to the limited length of each AS and BS. This technology can be applied to MPLS, ATM, SONET, WDM and other high-speed link layers under the evolving G-MPLS framework.

  • Patent number: 7286531
    Abstract: The invention provides a novel method to reduce the minimum offset time and pre-transmission delay for data in Optical Burst Switching or Labeled Optical Burst Switching or other packet or burst switched systems, as well as in circuit-switched networks. Under this method, a control packet is relayed as soon as it is determined if bandwidth for the data at the output port(s) can be reserved successfully, greatly speeding up the setup and configuration of the Switching Elements. A control packet is processed by a pipeline with up to 6 stages, and in addition, a control packet is processed using multiple processors at each port to speed up the time taken to determine if bandwidth for the corresponding data at the desired output port(s) can be reserved successful.

  • Publication number: 20040063461
    Abstract: A method consisting of the application of several novel algorithms to reduce contention and loss rates at remote (downstream) nodes Labeled Optical Burst Switched (LOBS), Optical Burst Switched (OBS), Optical Packet Switched (OPS) or other networks having buffer memory at an ingress nodes and optionally having buffer memory, FDLs or other signal delay devices at intermediate (downstream) nodes. Contention and loss are reduced by delaying locally assembled bursts beyond the pre-determined offset time using the electronic memory available at the ingress nodes, or delaying transit bursts using fiber delay lines (FDLs) even though there is no contention without using FDLs at all or a smaller delay is sufficient to avoid contention at this intermediate node. Compared to existing algorithms that address contention locally (or reactively), the proposed algorithms significantly reduce the burst loss rate.
