1. A method of conserving power in a first wireless network node on a wireless network having a plurality of network nodes, the first network node having a depletable power source having a remaining power capacity, the method comprising:
- detecting at the first wireless network node the remaining power capacity of the depletable power source;
comparing the remaining power capacity of the depletable power source to a plurality of sleep level thresholds, the sleep level thresholds each being associated with a different respective remaining power capacity level and being associated with a respective sleep level, each sleep level having at least one requirement;
selecting based on the step of comparing a sleep level for the first wireless network node to enter; and
transmitting to one or more of the plurality of network nodes an identification of the selected sleep level, whereby subsequent communication to and from the first wireless network node are consistent with the at least one requirement of the selected sleep level.

Abstract
A network node selects a “sleep” level based on its current or projected battery capacity. In an embodiment of the invention, sleep levels define the types of communication to which the node in question will be a party. The node in question communicates its selected sleep level to the rest of the network so that the other network nodes can communicate accordingly with the node.

27. A wireless network node having a depletable power source having a remaining capacity, the node comprising:
-
a connection module for detecting that one or more other wireless devices are within communication range of the wireless network node and for establishing respective connections with the one or more other detected nodes;
a power management module for evaluating the remaining capacity of the depletable power source and for determining a sleep level, from a plurality of available sleep levels, for the wireless network node based on the remaining capacity, wherein each sleep level comprises at least one requirement, and for transmitting an indication of the determined sleep level to the one or more other wireless devices. - View Dependent Claims (28, 29)
