Method for reporting and accumulating data in a wireless communication network

摘要

A method and apparatus for coordinating communication in a wireless sensor network may include a plurality of nodes, such as routers, edge nodes, data accumulators and/or gateways. Time management functions, such as determining an elapsed time, may be controlled based on a detected temperature, e.g., a temperature detected at a node, and/or based on a detected clock skew between two or more clocks in two or more different devices. Accurate time management may allow for devices to more accurately coordinate communication instances, e.g., communication that occurs at periodic wake up times. A cluster head, such as a data accumulator, may be associated with a network after its initial formation and cause nodes in the network to alter their hierarchy in the network, thereby making the cluster head accumulator a parent to nodes in the network. Nodes having a relatively lower hop count may have a higher battery capacity than nodes having a higher hop count.

1. A method for coordinating communication in a wireless sensor network, comprising:
associating a first node with the wireless sensor network including at least two nodes associated with each other in a parent/child relationship, the first node being associated with the wireless sensor network such that the first node functions as a parent or child to at least one other node; and determining a wake up time for the first node to wake up and listen for or broadcast a signal regarding communication with a parent or child node, the wake up time being determined based on a detected temperature at the first node.
