摘要:
A communication system for sending small data message is disclosed in which a user node receives data from a remote application program which is sent as a message to a central application program executing on a central hub. The user nodes sends the message to an access node using a first radio interface and the access nodes forward the message to a gateway node which relays the message to the hub over a second radio interface. The system also includes composite nodes which either implement access node and gateway node functionality, or switch operational modes between access nodes and gateway node functions. The mode switching can be triggered based on proximity to access nodes, or by instructions from a hub. The gateway nodes can implement a message storage function, and can be implemented as software defined radios.

A multi-hop heterogeneous wireless network is partitioned into a set of subnetworks including a first subnetwork having a first sink node and a second subnetwork having a second sink node. A node forms parts of the first and the second subnetworks and has different modes of operations (MOP) depending on the subnetwork. For example, the node has a first MOP specifying a type of the routing in the first subnetwork and a second MOP specifying a type of the routing in the second subnetwork. The node determines the MOD based on available routing resource of the node that is independent from the subnetwork and based on required routing resource that varies among the subnetworks. The node routs packets in the first subnetwork according to the first MOP and routing packets in the second subnetwork according to the second MOP.

A radio communication method capable of eliminating a blocking effect caused by a collision of many pieces of data is provided. The radio communication method relaying data from a lower terminal to an upper terminal, includes: a step of determining the number of lower terminals connectable to the upper terminal; a step of connecting the lower terminal and the upper terminal based on the determined connectable number; a step of transmitting a first data from the lower terminal to the upper terminal connected to each other; a step of causing the upper terminal to receive the first data transmitted from the lower terminal; and a step of combining the first data received by the upper terminal and a second data to be transmitted from the upper terminal and creating combined data; and a step causing the upper terminal transmitting the combined data to a further upper terminal.
摘要:
Embodiments disclosed herein include a wireless charging system configured to generate and transmit power waves that, due to physical waveform characteristics converge at a predetermined location in a transmission field to generate a pocket of energy. Receivers associated with an electronic device being powered by the wireless charging system, may extract energy from these pockets of energy and then convert that energy into usable electric power for the electronic device associated with a respective receiver. The pocket of energy may manifest as a three-dimensional field (e.g., transmission field) where energy may be harvested by a receiver positioned within or nearby the pocket of energy. Video sensors capture actual video images of fields of view within the transmission field, and a processor identifies selected objects, selected events, and/or selected locations within the captured video images.
摘要:
Data is bicasted to a wireless terminal over a wireless at least two air interfaces. Feedback on the data transferred over one of the air interfaces is obtained. An extent of future use of said one of said air interfaces to said wireless terminal at least in part may be determined on the basis of the obtained feedback. Feedback on the data obtained over at least one of the air interfaces is provided in response to bicasting of the data or in response to an indication sent to the wireless terminal.

A method for determining a source and a transmission path to provide content includes receiving a message comprising at least one of channel information of a link between a request device which requests content download and a central management device, available resource amount information of a candidate device, channel information of a link between the candidate device and the central management device, and channel information of a link between the request device and one candidate device. The method also includes determining a source device and the transmission path for providing the content to the request device using an available resource amount of the candidate device, a data rate of the link between the request device and the central management device, a data rate of the link between the request device and the candidate device, and a data rate of the link between the candidate device and the central management device.
