Abstract: Embodiments enable privacy protection for increasing service anonymity. A method comprises receiving a service discovery frame from a wireless device operating synchronously in a neighbor awareness network cluster, including scrambled values associated with service names, each of the scrambled values being a hash of an argument comprising the service name and a component value selected based on a current synchronous time shared with the wireless device. The received scrambled values are compared with scrambled values associated with maintained service names, each being a hash of an argument comprising a valid service name of a known service and a component value selected based on the current synchronous time. If any of the received scrambled values satisfies the comparison with a scrambled value associated with the service name, then the received scrambled value is determined to be associated with the known service.

Abstract: Service discovery for services on a wireless network is presented. It is determined (e.g., from a received Layer 2 message) that an offering apparatus h made a service available to entities joined to a wireless network. Then in a message, that is available to entities not joined to the network, is placed information about the services and also at least one of location information about the offering apparatus and link metric information about a network path to the offering apparatus. A discovering apparatus reads one or more transmitted messages (from different apparatuses in the same network in different networks), sees the service it wants is available through both, compares the different locations and/or the different link metrics, and based on the comparing chooses which network to join, or with which apparatus on the single network to create a peer link.

Abstract: Various embodiments are disclosed relating to techniques for RTS/CTS usage in a wireless network. According to an example embodiment, a network performance may be measured within a wireless network. A variety of parameters may be measured at a wireless node to determine a network performance.
