Abstract: An access point may advertise (e.g., broadcast) identifying information (e.g., a neighbor report and access point capability information) on a dedicated channel in a wireless network. The identifying information may include information about neighboring access points in the wireless network. The neighboring access points may operate on the dedicated channel, a different primary operating channel, or a combination thereof. A station entering the wireless network may scan the dedicated channel to detect the identifying information from the access point to aid relatively quick discovery of the neighboring access points without scanning multiple channels.

Accordingly, a message of a protocol for reserving a public network address and port may be used to indicate whether a network connection should be checkpointed for high availability.

Abstract: An apparatus and methods are provided for opportunistically conducting data communications on multiple wireless channels. In these methods, a device is engaged in data communications with a second device and receives a conflicting communication demand requiring action on one or more channels other than the data-communication channel (e.g., to conduct a channel scan, to issue or receive a beacon). The device arranges a schedule of channel switches to satisfy the communication demand and advises the second device of the schedule, and may explicitly invite the second device to implement the schedule. To the extent the second device does so, the data communications continue on the other channels. The devices may be participating in a synchronized peer-to-peer communication environment that requires their attendance on the data-communication channel and that is not associated with the other channels.

Abstract: Embodiments of the apparatus for modifying packet headers relate to a rewrite engine that represents each protocol header of packets in a generic format specific to that protocol to enable programmable modifications of packets, resulting in hardware and software flexibility in modifying packet headers. Software programs generic formats in a hardware table for various protocols. The rewrite engine is able to detect missing fields from a protocol header and is able to expand the protocol header to a maximum size such that the protocol header contains all possible fields of that protocol. Each of the fields has the same offset irrespective of which variation of the protocol the protocol header corresponds to. The expanded protocol header is represented by a data structure that is independent of a size of the protocol header.

Abstract: A sensor node executes any one among a first operation by which another sensor node is requested to execute data process and if the request is not accepted the sensor node starts executing the data processing after waiting for charging and a second operation by which the sensor node starts executing the data processing after waiting for charging, without requesting the data processing to be executed. The sensor node compares an expected value of a first time that elapses until execution is started by the sensor node or the other sensor node when the first operation is executed, and a second time that elapses until execution is started by the sensor node when the second operation is executed. Based on the comparison result, the sensor node executes among the first operation and the second operation, the operation for which the time that elapses until execution is started is shorter.

The at least one packet transmitted by the station includes data representative of the succession of binary values assigned to the station for the selection rounds.

Abstract: Embodiments of the apparatus for forming a hash input from packet contents relate to a programmable flexible solution to form hash inputs, allowing for hardware changes and for adding support for newer protocols as and when they are defined in the future. A packet is split into individual layers. Each layer is given a unique layer type number that helps identify what that layer is. Based on the layer type, each layer is expanded to a generic format. Each layer has a set of hash commands that is generic to that layer. Fields of each hash command are fieldOffset, fieldLen, hashMask, and hashMaskMSB. These hash commands allow information in the packet to be extracted in a programmable manner. The fields extracted from each protocol layer of the packet are concatenated to form a hash layer. A bit vector indicates which hash layers are used to form the hash input.
