In the next hop determination processing, the next hop determination unit randomly selects one from the candidates of the next hop node regarding a target node and updates the target node to the selected one. The next hop determination unit determines the communication route one-hop by one-hop by initializing the target node to the source node and then repeating the next hop determination processing until the target node becomes the destination node. | 2011-10-27 |

Options for allocating dedicated signatures include allocating the dedicated signature from the unused space of the random signature root index when there is unused space and allocating more dedicated signatures from the same root index using the same time/frequency resources if additional signatures are needed, and reserving some preambles from the contention-based random access preambles from both sets of preambles. The present invention also proposes that the dedicated signatures be reserved in each of two sets of preambles. | 2011-10-27 |
20110261753 | ENABLING IPv6 MOBILITY WITH SENSING FEATURES FOR AD-HOC NETWORKS DERIVED FROM LONG TERM EVOLUTION NETWORKS - A wireless communication device includes a plurality of different wireless interfaces to facilitate communications with a remote device over a corresponding plurality of networks. The device can switch between the different interfaces to migrate an on-going communications session from one that requires the infrastructure of a fixed wireless communication network to one that does not require the infrastructure of a fixed wireless communication network. Switching between the various interfaces allows the migration to occur while protecting the device against malicious third-party impersonation attacks. | 2011-10-27 |
