Various embodiments are described relating to selecting anchor nodes among nodes in a wireless network. In an example embodiment, a topological arrangement of a first wireless node and one or more other wireless nodes neighboring to the first wireless node in a wireless network may be determined by the first wireless node. A second wireless node may be selected to perform anchor node operations for the first wireless node based on the determined topological arrangement. For example, the first wireless node may select itself to perform the anchor node operations based on the determined topological arrangement.

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.

Multiple nodes communicate using repeating patterns of superframes, where each of the superframes includes a beacon period. A beacon slot in a first Media Access Slot (MAS) is reserved by the plurality of nodes. This reserved slot occurs in the beginning of the beacon period and is used for communicating information relating to the superframe configuration. This information may involve adjustments to the number of MASs reserved for beaconing.

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.

There is featured a Direct Mode (DM) communication method between two mobile terminals (MTs) in access point (AP) controlled WLAN systems. The DM connection scheme calls for establishing that an initiating MT and a remote MT are associated to the same AP; establishing that the remote MT supports a DM operation feature; sending, by the AP, address identifiers of the initiating and remote MTs to the remote and initiating MTs, respectively; and sending, to the AP, RSS measurements performed by the initiating and remote MTs of MT identifying messages sent to them by the remote and initiating MTs, respectively. DM communication between the two MTs continues with exchange of information to conclusion when a MT identifying message is satisfactorily received by both MTs and when a MT identifying message of either MT is not satisfactorily received, DM communication setup is terminated.

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.

Method, apparatus, and computer program product embodiments are disclosed to provide for wireless resource sharing on a fair basis between heterogeneous wireless networks to enable coexistence in a TV band white space. An example embodiment of the invention includes a method, comprising the steps of: receiving a coexistence value associated with a wireless network; receiving radio frequency spectral environment information of the wireless network; receiving coexistence values and radio frequency spectral environment information of wireless networks neighboring the wireless network; receiving a resource request for the wireless network; generating a resource allocation based at least on the received coexistence values and received radio frequency spectral environment information; and communicating at least a portion of the generated resource allocation to the wireless network. The resulting embodiments provide for wireless resource sharing on a fair basis between heterogeneous wireless networks to enable coexistence of secondary networks.
摘要:
An apparatus (STA) receives from a first node (AP1) at least one channel access related parameter and a first congestion indication; and receives from a second node (AP2) a second congestion indication. The apparatus determines a combined congestion indication which is based at least on the first congestion indication and the second congestion indication; and determines a first channel access parameter for a channel between the apparatus and the first node based at least partly on the at least one channel access related parameter and the combined congestion indication. In specific embodiments, the channel access related parameters may be an initial EDCA parameter and a degradation factor.
