摘要： A method for proximity detection in a wireless communication network. A node attempts to determine the proximity of the closest neighboring node by transmitting a ranging request. Other nodes respond, and the first node to receive and respond to the request will have the shortest response time and thus will be the closest node. Exact ranges can be determined by applying Time-Of-Arrival (TOA) techniques to node response times. To further avoid collisions, one or more frames of the response messages can be same, making the multiple responses appear as multi-path. The group of responders can be narrowed and individual groups probed in a search pattern until the single nearest node is known or range of the nearest node is known. The ranging node may then use ordinary unicast mechanisms to probe this node, or begin scanning the groups again, or interleave the two mechanisms as desired.

摘要： Methods and apparatus are provided for determining and representing a location or position of a node in a network. When the node receives position measurement information from a reference node, the node generates, based on the position measurement information, a position probability space (PPS) which defines a space that encompasses possible positions where the node is possibly positioned in the network. The PPS includes a centroid (i.e., a set of coordinates), and a set of vectors which originate from the centroid and define the space around the centroid. The magnitude of each vector reflects the accuracy of the position in the direction of the vector.

摘要： A method and apparatus for calculating a location of a device is provided. A likelihood of the device being located at a particular location point or a particular location floor is determined using a likelihood calculation at each of a plurality of locations. The location point or location floor is then identified as that location having an associated highest likelihood calculation. The likelihood calculation includes calculating a distance from the device to each of a plurality of reference routers including one or more virtual coplanar reference routers, wherein each of the one or more virtual coplanar reference routers comprise a projection of a non-coplanar reference router onto the floor.

摘要： In a wireless multi-hop network including a plurality of multi-radio meshed nodes, a method is provided for a particular recipient multi-radio meshed node to optimize a route to an intelligent access point (IAP). Each of the multi-radio meshed nodes include a plurality of radio modules, and each radio module comprises an interface.

摘要： Techniques are provided for determining a position of a node. For example, the node receives first position data from a first reference node and second position data from a second reference node. The second position data includes second position measurement information and a precision indicator which indicates accuracy of the second position measurement information. The node generates a timestamp which indicates when the second position data was received by node, and storing the second position data and associated timestamp. Upon receiving updated first position data at the node from the first reference node, the node determines whether updated second position data has been received from the second reference node, and if not, generates aged second position data based on the stored second position data and the associated timestamp. The node can then determine its position based on the aged second position data and the updated first position data.
