摘要:
Systems and methods are provided that facilitate distributed multichannel wireless communication and provide the highest level quality of service (“QoS”) guarantee and support extremely high bandwidth applications such as voice over internet protocol (“VOIP”) streaming audio and video content (including high definition), and multicast applications and also supports convergent networks, ad hoc networks, and the like. A modular MAC architecture provides a group of nodes with the ability to simultaneously communicate with each other using multiple separate communication channels during the same timeslots. The additional throughput gained by employing multiple communication channels is amplified by dynamically mapping the communication channels and timeslots in a network so that multiple channels can be reused simultaneously throughout the network during the same timeslot in a fashion that does not create collisions.

摘要:
Systems and methods for determining a location of a device with a wireless network. Characteristics of signals received from the device at a plurality of nodes are measured. Based upon the measurements, estimates of the range from the device to the nodes are made. Then, based upon the estimated ranges, and knowing the location of the nodes, a location of the device is determined.

A scalable medium access control (“MAC”) module is provided that avoids conflict resource reservation so that network performance does not degrade as the number of hops or nodes in a wireless network increases. The MAC also provides different access schemes for traffic with different quality of service (“QoS”) requirements such that QoS is guaranteed and network resources are efficiently utilized. Furthermore, the resource allocation scheme determines the routing path as resources is allocated for data traffic, thereby achieving more robust layer-2 routing at the MAC layer. Finally, the scalable MAC is compliant with both WiMedia MAC and IEEE 802.15.3 MAC.

摘要:
A peer-to-peer (P2P) application which can be applied to TVs. The P2P application promotes a social networking aspect by allowing devices connecting to either the home mesh network and/or Internet to share contents and create common-interest channels. The P2P application does not require support from network infrastructure (e.g., no central servers), and consequently is extremely cost-effective and easy to deploy. The distributed nature of this system allows users to join or leave the network at will. It takes advantage of the local home mesh network connectivity, or existing Internet connections. A participant that tunes into a broadcast on an Internet channel is not only downloading a video stream, but also uploading it to other participants watching the program. Data mining systems capture user preferences and create personalized Internet channels on the TV using the P2P network.

A method to share, barter, lend, trade, rent and give energy through technology and peer communities. An online service which allows users to globally monitor, manage and redistribute energy (electricity) at the individual house level. This method of collaborative consumption gives members in the organized communities the benefit of ownership with reduced personal burden and costs. The fundamental value is that it provides an alternative to traditional forms of purchasing and ownership.
摘要:
An embodiment of the invention involves a method for selecting an infrastructure mode wireless channel for a tier-2 wireless node of a plurality of wireless nodes forming a wireless mesh network. The method comprises a first operation of receiving information from at least one neighboring node. Then, the first wireless node determines if a collision has occurred with the at least one neighboring node, where the collision is an overlapping of wireless channels selected by the first node and the at least one neighboring node. If a collision has occurred, the first wireless node compares its network degree, iterative count, and MAC address (progressively in that order) with that of its neighboring node to determine which of the first wireless node or the at least one neighboring node is responsible for re-selecting a different wireless channel from a set of non-overlapping wireless channels that are available to the wireless mesh network. Other embodiments are described and claimed.
