International Classification:

H04B001/38

US Classification:

455/555000, 455/561000

Abstract:

A wireless communication network comprises a plurality of wireless communication nodes, each wireless communication node comprising a first wireless access point and a second wireless access point coupled to the first wireless access point. The first wireless access point is configured in a first mode to wirelessly communicate with at least one wireless client and with a wireless access point of another wireless communication node. The second wireless access point is configured to wirelessly communicate with a wireless access point of a different other wireless communication node. Multiple wireless communication nodes according the present invention may be coupled together to form a wireless bridged network.

International Classification:

G06F 15/173

US Classification:

709224000

Abstract:

A system and method for improving digital communication in a wireless mobile ad-hoc network. More specifically, the system includes one or more portable network devices operable to support the seamless operation of a self-initializing, self-healing, adaptive portable network. The portable network devices implement protocols that provide bandwidth management capabilities for use with radios, routers and other wireless network devices. Each portable network device includes at least one wireless transceiver, a processor and control software. The processor and control software are logically coupled to the wireless transceiver to facilitate digital communication via a plurality of communication channels with other network devices.

Assignee:

International Classification:

H04W 40/02

US Classification:

370225

Abstract:

Traditional computer networks have been designed with the need for highly reliable packet delivery. This is largely handled by a centrally managed simple send-acknowledge protocol. In a highly dynamic mesh network, these methods are inadequate to ensure the most reliable packet delivery. This invention uses the natural redundancy of routes in a mesh and other techniques to increase the reliability of a network, even as the paths to any given node are dynamic in nature.

H04L 12/26

Abstract:

Computer networks with multiple nodes are often required to deliver packets to all nodes in the network, commonly referred to as “flooding.” Flooding is used to deliver multicast and broadcast packets generated by application, network and other layers of the networking stack. Flooding can be done very reliably but less efficiently via node to node “unicast” transmissions, or very efficiently but less reliably via “broadcast” transmissions. In order to balance reliability with efficiency, this invention defines a threshold for the number of neighboring nodes as seen by a given node prior to a flooding operation to determine whether data should be unicast or broadcast. Below that threshold, unicast is used; at or above that threshold, broadcast is used. The invention also incorporates knowledge of nodes seen in turn by neighbor nodes as part of this decision.
