David P Gurney, Wayne W Chiou, Randy L Ekl, Douglas H Weisman: Method for addressing user location errors in a cognitive radio system. Motorola, Motorola, March 5, 2009: US20090061779-A1

A cognitive radio (CR) system (102) includes CR units (108, 110) that determine and update location-based system operating parameters to avoid interference with other systems operating in the same frequency band. Operational Location Uncertainty region and Allowed Location Error regions can be appli ...

In order to set up efficient routes between two closely-located nodes an optimized route for two nodes within a hybrid-cellular network (HCN) is achieved by converting an HCN route to an ad-hoc route. Thus, a node within the communication system may originally be communicating with another node via ...

When a requesting node (402) has routing capabilities and attempts to join a network and there are no association slots available, the requesting node (402) will send an association message to a potential root node (401). If the root node (401) has reached the maximum number of links, and has a non- ...

A multi-routing protocol network (100, 200) and methods (400, 500) of operating wireless devices (102, 104) in the network that allow the network to be switched from one routing protocol to another are provided. Wireless devices initiate communication with devices that are already part of the networ ...

Jian Huang, Wayne W Chiou, Qicai Shi: Method and apparatus for a node to determine a proper duty cycle within an adhoc network. Motorola, Motorola, July 26, 2007: US20070174465-A1

A method and apparatus for determining a node's proper duty cycle is provided herein. All nodes (500) within a network (100) will interactively switch duty-cycles based on a number of hops a device is from a personal area network coordinator PNC. Changing duty cycles based on a number of hops from a ...

A method and apparatus for removing phantom children in an ad-hoc network is described herein. During operation messaging between the parent and child nodes allows the parent node to detect when a node has become a phantom node, and take action to correct it. In particular a maintenance message is p ...
