| 20120120883 | REGION-BASED CLUSTERING MECHANISM FOR CHANNEL ACCESS IN VEHICULAR AD HOC NETWORKS - In a Vehicular Ad Hoc Network (VANET) a hybrid method combines SDMA (Space Division Multiple Access) and dynamic TDMA (Time Division Multiple Access) that divides the roadway into regions (whose size is larger than the SDMA unit) where each region is allocated a pool of radio channels based on SDMA and may contain a limited number of vehicles. Vehicles within the same region compete for and access the channels using dynamic TDMA. A channel allocation scheme that maps the pool of channels to the regions such that when a vehicle acquires multiple channels (time slots) in a region, the intervals among the channels are as uniform as possible, thus minimizing the waiting time of the messages to be broadcast by the vehicle, which is critical for safety related applications. This solution is referred to as R-SDMA (Region based SDMA). | 05-17-2012 |
| 20100293289 | PEER-TO-PEER MOBILITY MANAGEMENT IN HETEROGENEOUS IPV4 NETWORKSAPP 1784n - Peer-to-peer mobility management in heterogeneous IP networks provides a peer-to-peer mobility module operable to intercept a data packet received at a communication protocol layer of an Internet Protocol communication stack. A translation table may be stored on memory device. The translation table stores real address of one or more network interfaces and a corresponding virtual address. The peer-to-peer mobility module may be further operable to modify the intercepted data packet using the real address and virtual address stored on the translation table. | 11-18-2010 |
| 20100290378 | ASYMMETRIC AND ASYNCHRONOUS ENERGY CONSERVATION PROTOCOL FOR VEHICULAR NETWORKS - An asymmetric and asynchronous energy conservation protocol for vehicular networks is provided. In one aspect, an a-quorum may be defined for one or more members for the one or more members to establish asymmetric links to contact the cluster head. An s-quorum for the cluster head to establish symmetric link between the cluster heads and relays may be defined. | 11-18-2010 |
