WIRELESS SENSOR NODE DATA TRANSMISSION METHOD AND APPARATUS
First Claim
1. A method comprising:
- at a wireless sensor node that is downstream from a second wireless sensor node;
providing data as corresponds to a sensed condition, which data is to be wirelessly transmitted upstream towards a collection point via the second wireless sensor node;
determining when to transmit the data to the second wireless sensor node as a function, at least in part, of data aggregation opportunities as may exist with respect to the second wireless sensor node.

Abstract
Generally speaking, pursuant to these various embodiments, a wireless sensor node (200) that is downstream of another wireless sensor node can provide (101) data as corresponds to a sensed condition and which is to be wirelessly transmitted upstream to a collection point via that other wireless sensor node and then determine (102) when to transmit that data as a function, at least in part, of data aggregation opportunities as may exist with respect to that other wireless sensor node. By one approach, a given data aggregation opportunity can comprise, for example, aggregating data regarding a plurality of temporally-differentiated sensed conditions and/or aggregating data from a plurality of wireless sensor nodes (such as, but not limited to, yet another wireless sensor node that is also downstream of the other wireless sensor node). By one optional approach, if desired, the wireless sensor node can determine when to transmit such data as a function of both data aggregation opportunities as are mentioned above as well as quality of service requirements as may otherwise pertain to the data. Relevant quality of service requirements might comprise, but are not limited to, a timeframe within which the data is to be provided to the upstream collection point.

16. A method comprising:
-
providing a plurality of wireless sensor nodes and a data collection point; when a first wireless sensor node must wirelessly provide sensor data to the data collection point via at least one intermediary wireless sensor node; determining at the first wireless sensor node that a data aggregation opportunity exists with respect to the intermediary wireless sensor node; upon determining that the data aggregation opportunity exists, dynamically arranging at the first wireless sensor node for transmission of the data to the intermediary wireless sensor node in a manner that tends to exploit the data aggregation opportunity. - View Dependent Claims (17, 18, 19)
