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。
