20090296571 | SYSTEM, METHOD AND PROGRAM FOR DETERMINING FAILURE IN NETWORK COMMUNICATION - System, method and program product for determining a cause of a failure of a communication from a source device to a destination device. A preferred route from the source device to the destination device comprises a series of routers in a forward order. First program instructions determine one or more initial routers in the series in the forward order from the source device toward the destination device. A last of the initial routers does not designate a next router in the series in the forward order toward the destination device. Second program instructions determine the series of routers in a reverse order from the destination device toward the source device. Third program instructions determine from the series of routers in reverse order as determined by the second program instructions which router the last of the initial routers should designate as its next router in the forward order toward the destination device, and send a notification as to which router the last of the initial routers should designate as its next router in the forward order toward the destination device. | 2009-12-03 |

20090296667 | Communication Method In Mobile Communication System, And Mobile Station And Base Station In The Same System - A scheduling method for transmitting an uplink signal from a mobile station to a base station comprises transmitting the uplink signal in a first scheduling mode in which the mobile station can transmit the uplink data without permission of the base station if an uplink communication state between the base station and the mobile station is higher than or equal to a predetermined quality; and transmitting the uplink signal in a second scheduling mode in which the permission is necessary for the mobile station transmitting the uplink data if the uplink communication state is lower than the predetermined quality. | 2009-12-03 |
20090296668 | Method For Controlling Access To TDMA Wireless Channel Form Nodes Of Network Of Either Linear Or Tree Topology - Requests of resources of uplink flows towards a base station (BS) and/or downlink flows towards end nodes are computed by each requesting node on an end-to-end basis. Each requesting node issues a cumulative request given by summing up the same request for each link separating the node from the BS plus each link separating the BS from the destination node, enabling the centralized node to perform connection based scheduling. The BS in response to all cumulative requests grants uplink and/or downlink resources for each link. The profile of grants is equal to the profile of requests when the amount of resources requested is below the maximum net throughput on MAC layer. When not below the maximum net through-put on MAC layer, the ideal profile of grants is normalized with respect to a ratio between the maximum net throughput on MAC layer and the amount of the overall requested resources. | 2009-12-03 |
20090296669 | Access control system in wirelesss lan system - In a wireless LAN system using an access point to perform access control for accesses from a plurality of client terminals, an access point and each of a plurality of client terminals have a transmission means using a data transmission carrier wave frequency and a control signal transmission carrier wave frequency; each of the plurality of client terminals has a memory storing priority information; when the data transmission carrier wave frequency is not sensed on the wireless LAN, data are transmitted to the access point at a relevant data transmission carrier wave frequency; when the data transmission carrier wave frequency is sensed on the wireless LAN, a band reservation request is sent to the access point at a relevant control signal transmission carrier wave frequency along with priority information stored in the memory; and after a transmission confirmation is received from the access point for the band reservation request, data is transmitted to the access point at a relevant data transmission carrier wave frequency. | 2009-12-03 |
20090296670 | PULL-BASED DATA TRANSMISSION APPROACH - A network can include a number of nodes that link a source node to a sink node. When a first node in a network sends a packet to its downstream node, this information is also received at its upstream node. In response to learning that the first node has sent a packet, the upstream node sends another packet to the first node. In essence, a pull-based transmission approach is used to mitigate congestion and address the funneling effect in data transmission networks such as wireless video sensor networks. | 2009-12-03 |
