In another scheme, acquisition is performed on at least one frequency channel previously acquired for a radio technology (e.g., W-CDMA). A search for the radio technology is then performed using results of the acquisition to omit frequencies from the search.

The decoded information includes, e.g., type information indicating that a second band is allowed to be used for peer-peer communications and/or identification information identifying at least one of a wireless communications device which transmitted the beacon signal and a current user of the wireless communications device which transmitted the beacon signal.

Abstract: A method for providing frequency agility in a wireless network with a plurality of RF frequency channels. The nodes are formed into a hierarchical branching tree for communication. The RF environment for each of the plurality of RF channels is sensed as a function of time and the sensed measurements are stored. Based on the stored measurements of RF environment, a channel assignment scheme as a function of time is selected and transmitted to the network nodes. Nodes within the tree can be segmented geographically and assigned channels based on the sensed local RF environment. Nodes can also be segmented to reduce the density of nodes using the same assigned channels. Such frequency agility enhances the communication capability of a wireless sensor network in a harsh RF environment.

Abstract: Knowledge of the computational context of a computer operating environment, for example, awareness of process threads, is used to route IP traffic in the presence of multiple active network connections. An additional protocol may be added to the network layer of an operating system in order to map certain computational contexts to particular network interfaces. Any process with identification parameters associated with a mapped computational context requesting data transfer via a communication network is bound to the network interface previously associated with the computational context rather than an alternate network interface that otherwise might be the default. Further, process threads created by a parent process thread may be caused to inherit the computational context of the parent thread in order to assign traffic to the same network interface. This routing framework may have particular application with respect to multihomed host devices, for example, mobile computing devices.
