摘要： To address the need for channel assignment in an ad-hoc network, a method and apparatus for channel assignment is provided herein. In particular, a communication system (100) utilizes a method for deterministic node (101-107) channel assignment that enables channel reuse and thus scalability of an ad-hoc network. The channel assignment is dependent upon a current level for the particular nodes, as well as the maximum available channels, the maximum allowable levels in the network, and the maximum number of children nodes that a parent can have.

摘要： A method and system is provided for determining a location for each of a plurality of units, which are sub-divided into more than one sub-net groupings, that each include two or more units. Within each sub-net grouping, measured range information between units within the sub-nets and one or more reference units is gathered in at least a selected one of the units. The selected one of the units then estimates a location for each of the units, which minimizes any error in the measured ranges between the units in each of the corresponding sub-nets.

摘要： A method and apparatus for determining the location of a node within a communication system is provided herein. During operation, located nodes (105) having known locations are utilized to locate "blind" nodes (200) whose location is to be determined. More particularly, a blind node (200) wishing to determine its location will measure a plurality of signal strengths between itself and a plurality of located nodes (105). Each located node's signal strength will then be adjusted based on at least one antenna gain pattern. A radio-location algorithm will then be executed on the adjusted signal-strength measurements to determine the nodes location.

摘要： A location technique is utilized with a wireless communication system (100) where power measurements from various nodes (104,105) are weighted to determine anode's location. An iterative location process is executed where as more and more nodes (104,15) are heard from, a node (104,105) will re-locate itself in order to improve location accuracy.

摘要： A method and system is provided for determining a location for each of a plurality of units, which is selected from one of multiple sets of locations, which are each estimated based upon different initial location estimates. The selected set of locations includes the set which has the minimum error value, where the error value is based on the aggregate of the differences between the range determined from the estimated locations and the measured range. By using different sets of initial location estimates, there is a greater chance that at least one of the sets of initial location estimates will avoid any local minimums and produce a more accurate estimate of unit locations.

摘要： A method and apparatus for determining the path loss model of an object within a wireless communication system is provided herein. During operation, a path loss model for a node is generated based on path loss values and corresponding numbers of neighbors of the said node. The path loss model is used to determine a relationship between path loss and distance. With this relationship established, distances to known-located nodes may be obtained by obtaining a path loss to the known-located node. From these distances, a node can then be located.

摘要： A communications network (100) has coordinator devices (10) each transmitting a beacon message in a cluster area (30). Neighboring coordinator devices (1, 2) define overlap areas (60) in which each beacon message of the neighboring coordinator devices is present. Neighboring coordinator devices (1, 2) may also define non-overlap areas (204) in which each beacon message is present. A method for distributing communication signals includes providing nodes (50), (51,52) within a transmission region (30) of the coordinator devices (1, 2). The node (50) or nodes (51, 52) detect at least one beacon message of the neighboring coordinator devices (1, 2), determine the existence of a condition (302), and warn neighboring coordinator devices of the condition. The condition (302) is corrected by making an adjustment to the communication signal (such as beacon timing) by a correction amount (304).
