摘要:
Various embodiments are described relating to resource management techniques for wireless networks. For example, a resource deficiency may be determined for a requesting wireless node in a wireless network. A resource request may be sent from the requesting node to one or more other wireless nodes, and a resource reply including a resource status may be received from one or more of the other wireless nodes in response to the resource request. One of the other nodes from which to obtain a resource may be selected based on the resource status for the selected node, and a resource update message may be sent from the requesting wireless node to the selected wireless node to facilitate a reallocation of resources from the selected node to the requesting node, the resource update message indicating an amount of resources to be reallocated from the selected node to the requesting node.

Various embodiments are disclosed relating to pro-active congestion mitigation in wireless networks. In an example embodiment, a wireless node may make a determination that an amount of previous channel usage by the wireless node is greater than a threshold value, and then delay an acquisition of a transmission opportunity based on the determination. For example, the wireless node may delay a start of a backoff time counter based on the determination, and/or may increase a value of the backoff time counter based on the determination.

A method, system, and computer program product are disclosed for providing a forwarding feature in the WiMedia MAC communication protocol or in other suitable communication protocols. The method enables a forwarder device to indicate its capability to operate as a forwarder device in its beacon transmissions and to enable an initiating device to utilize the forwarder device for communicating data and/or network control information to destination devices that can be accessed through the forwarder device over two or more hops.

A method, system and program code are provided to implement a wireless network having a plurality of devices in which one of the devices coordinates wireless communications between the devices. The method and system evaluates device parameters of one or more of the plurality of devices, the device parameters including at least available power source characteristics for a device; and determines a coordinator from the plurality of devices based on at least the available power source characteristics, such as an available power source capacity, for the one or more of the plurality of devices, the coordinator adapted to coordinate wireless communications between the devices in the wireless network.
摘要:
A wireless communications device detects a change in its residual energy status, and transmits the residual energy status across a wireless communications network to a remote device that coordinates communications in the wireless communications network. For example, the remote device may be a piconet coordinator (PNC) in an IEEE 802.15.3 network, or a master device in a Bluetooth network. A wireless communications device that coordinates communications in a wireless communications network (the coordinator) transmits one or more first handover commands to one or more remote devices upon the occurrence of a triggering event. Based on responses to these first commands, the coordinator selects a remote device for coordinating future communications in the wireless communications network.

A method and system improves data throughput when performing error control in Ultra Wideband (UWB) communications. The method and system is capable of performing communications via a first wireless communications link and a second wireless communications link. The first wireless communications link is a UWB transmission link and the second wireless communications link is a different type of wireless communications link for communicating error control data for the UWB transmission link.
摘要:
A wireless device transmits beacon packets at periodically occurring time intervals across a wireless channel. When the wireless communications device has not formed a piconet with one or more remote devices, the device scans the wireless channel for a predetermined amount of time immediately following each of the periodically occurring time intervals. During this time a remote device may respond to the beacon packet.

Various embodiments are described relating to sharing scanning operations among nodes in a wireless network, such as a WiMedia ultra-wideband (UWB) network. In an example embodiment, a message may be sent from a first node to one or more other nodes in a wireless network indicating that the first node is configured to perform a scanning operation on a wireless medium in substitution of scanning the wireless medium at the one or more other nodes. The wireless medium may be scanned, for example, by the first node to obtain scanning results for the one or more other nodes. The scanning results may be sent, for example, by the first node, to the one or more other nodes.
摘要:
Generating a protected content stream from a data stream provides enhanced security in short-range wireless communications networks. This protected content stream is transmitted across a first short-range communications link. In addition, information for converting the protected content stream into the data stream is transmitted across a second link. The first link may be an ultra wideband (UWB) link, while the second link may be a Bluetooth link.
