Abstract: An additional cyclic redundancy check (CRC) is inserted in IEEE 802.11 beacon or data frames prior to the end of the frame, at a location following information sufficient for the receiving station to determine whether the frame is from an overlapping basic service set or intended for a different station and to extract other necessary or useful information such as a time of the next full beacon. Upon detecting the CRC, the receiving STA can terminate reception of the frame early to conserve power, and then enter a low power operational mode to further conserve power.

A first wireless device (e.g., a wireless access point) that serves a plurality of second wireless devices (e.g., client devices) in a wireless network, groups the plurality of second wireless devices into sets based on commonality of the second wireless devices in terms of one or more of: power requirements and throughput requirements. A time interval on a wireless channel during which the second wireless devices may contend for usage of the wireless medium is partitioned into a plurality of disjoint or overlapping contention periods. Each set of second wireless devices is assigned to a corresponding one of the plurality of contention periods such that only second wireless devices in each set contend for access to the wireless channel during the corresponding contention period assigned to that set.

Abstract: Methods of reassembling a mesh network which has been disrupted by the unavailability of a node or a link are disclosed. Nodes continuously receive beacon messages originating from a leader node. These beacon messages may be transmitted directly by the leader node, or may have been retransmitted by an intermediate node. When a node determines that it has not received a beacon message in a certain time period, it concludes that it is now disconnected from that leader node. At this point, it may choose to act as a leader node and form a new network, or may join with another network. The determination of which network to join may be based on some indicia associated with the leader node of that network.

Abstract: A method of efficiently disseminating various types of information throughout a mesh network is disclosed. Information is typically propagated through the network using a variety of protocols and messages. However, in one embodiment, a single message, communicates all of this information at once. The message includes data originating at the leader, which does not change as the messages are propagated through the network, as well as topology and link information that is created by the forwarding nodes. The data originating at the leader includes the identity of the leader node and a sequence number. Additionally, a version number is included by the leader which represents the state of the quasi-static information. Quasi-static information may include, for example, the identity of a node that has access to a central control system or the internet. This compact message format allows improved efficiency and use of the network.

Abstract: At least two different redundancy protocols are operated in parallel by network devices in an Ethernet network. Control is determined and assigned to one of two protocols to have total control over which ports in the network devices are active and which are blocked for transmission of user data and network data network traffic while allowing all control and monitor traffic to traverse the ring of network devices. Control and monitoring packets are transmitted by RSTP packets through all of the network devices in the ring while restricting the data ports of the network devices to transmit user data and data network traffic to the network devices connected in the line of the network devices. Parameters received in RSTP packets are collected from all of the network devices in the ring in order to determine which network device of the network devices is a virtual root bridge.
