摘要： An invention is disclosed whereby a wireless network node, equipped with two or more radio transceivers statically tuned to non-interfering frequency channels, can make decisions regarding which channel to use when communicating with a neighboring wireless node. A multi-radio unification protocol implemented in a wireless node coordinates the use of multiple wireless network interface cards and provides a virtual layer that hides the multiple physical network interfaces from higher layers of a node's network protocol stack. The invention is applicable to wireless networks generally, including those in which some nodes do not have multiple radios or do not recognize the multi-radio unification protocol. The invention makes possible simultaneous transmissions using available channels, thereby reducing interference and delay while increasing the overall capacity of the network.

摘要： Described herein is an implementation that reduces the battery consumption of an energy-constrained computing device that is capable of communicating over a wireless network. As conditions and circumstances warrant, the implementation selects one of multiple radios (e.g., two)—with each having a unique combination of characteristics (in terms of power-consumption, data-rate, range and/or frequency band of operation) for wireless communications to and from a wireless device. The implementation selects one radio to minimize power-consumption while maintaining effective wireless data communication. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.

摘要： Disclosed is a Neighbor Location Discovery Protocol (NLDP) that determines the relative locations of the nodes in a mesh network. In one embodiment, NLDP can be implemented for an ad-hoc wireless network where the nodes are equipped with directional antennas and are not able to use GPS. While NLDP relies on nodes having at least two RF transceivers, it offers significant advantages over previously proposed protocols that employ only one RF transceiver. In NLDP antenna hardware is simple, easy to implement, and readily available. Further, NLDP exploits the host node's ability to operate simultaneously over non-overlapping channels to quickly converge on the neighbor's location. NLDP is limited by the range of the control channel, which operates in a omni-directional fashion. However, by choosing a low frequency band, high power, and low data rate, the range of the control channel can be increased to match the range on the data channel.
摘要翻译：公开了一种确定网状网络中节点的相对位置的邻居位置发现协议（NLDP）。在一个实施例中，可以为节点配备定向天线并且不能使用GPS的自组织无线网络实现NLDP。虽然NLDP依赖于具有至少两个RF收发器的节点，但是与先前提出的仅使用一个RF收发器的协议相比，它提供了显着的优点。在NLDP天线硬件中，简单易用，易于实现。此外，NLDP利用主机节点在非重叠信道上同时操作的能力，以快速收敛在邻居的位置。 NLDP受限于以全向方式运行的控制通道的范围。然而，通过选择低频带，高功率和低数据速率，可以增加控制信道的范围以匹配数据信道上的范围。

摘要： Implementation of opportunistic use of stations in a wireless network as repeaters is described. In one implementation, a station detects the existence of rate anomaly in a wireless network. In response to the rate anomaly, the station may transform into a software repeater for certain other neighboring stations. The repeater function allows for the relaying of packets sent by these neighboring stations to the access point and vice versa. The other neighboring stations, owing to their relative proximity to the repeater station, transmit data at a higher rate to the repeater station. Thus, the removal of the slower stations reduces clogging of the access point and increases the overall data rate within the wireless network. Further, a zero-overhead network coding protocol may be implemented in conjunction with the repeater function to increase capacity of the wireless network.

摘要： A new system and method of available bandwidth estimation applies even where the narrow link and tight link in a network path are in different locations. In embodiments of the invention, a unique packet probe series structure and processing is employed to estimate available bandwidth. In an embodiment of the invention, the spacing between probe packets is adjusted at the source to account for dilation caused by links leading to the tight link, so that the spacing is appropriate when the probes arrive at the tight link. Moreover, the multi-packet probe comprises a large packet followed by two much smaller packets. The large packet is then dropped once it has traversed the tight link. The two small packets, which are impacted little by subsequent narrow links, preserve the spacing set by the tight link, encoding the delay induced by the tight link, all the way to the destination.

摘要： A system and method for link quality routing uses a weighted cumulative expected transmission time path metric. A system for routing in a multi-hop ad hoc network, and a method for measuring the link quality of a route in the network, include assignment of a weight to a link in accordance with an expected transmission time of a packet over the link, and a combining of individual link weights for a route into a path metric. The path metric accounts for interference among links that use a shared channel. In the calculation of the path metric, the expected transmission times of links that interfere with one another are added, while the expected transmission times for non-interfering links are considered separately.
