Determining Node Location Based on Context Data in a Wireless Node Network

摘要

Methods and systems for determining an improved location of a node in a wireless node network based on context data are described. A network device, such as a master node or server, accesses a first type of the context data related to a proximate environment of the node being located. The first type of the context data includes signal degradation information for a second node (similar to the first node) in a similar environment to the proximate environment of the first node. Based upon this first type of context data, the network device adjusts a communication distance related to the first node, such as a transmission distance or receiver sensitivity range distance. The network device then determines the improved location of the first node based upon the adjusted communication distance that accounts for signal degradation known to affect the similar second node in the similar environment.

1. A method for determining an improved location of a first node in a wireless node network based on context data and by a network device deployed in the wireless node network, the method comprising:
accessing, by the network device, a first type of the context data related to a proximate environment of the first node, wherein the first type of the context data comprises signal degradation information on how a second node would operate in a similar environment to the proximate environment of the first node when the second node is a similar type as the first node; adjusting, by the network device, an anticipated communication distance related to the first node based upon on the first type of the context data; determining, by the network device, the improved location of the first node based upon the adjusted communication distance; and storing, by the network device, the determined improved location of the first node as part of location data maintained on a memory storage of the network device.
