Abstract:
1. A method for wireless network operation comprising: receiving an indication that a first communication node is designated for operation in a limited communication mode, wherein the first communication node is included in a wireless network comprising a central node and a plurality of communication nodes in wireless communication with the central node, each of the communication nodes having a wireless communication path to the central node that is either a direct path or an indirect path through one or more intermediate communication nodes serving as relays, wherein one or more of the communication nodes operate in the limited communication mode in which they are scheduled to transmit data less frequently than one or more other communication nodes not operating in the limited communication mode; and scheduling reading of data from the first communication node to be performed less frequently than reading of data from the one or more other communication nodes not operating in the limited communication mode, wherein, for each of the one or more other communication nodes not operating in the limited communication mode, when the central node does not receive an indication that the communication node has performed a network transmission within a first threshold time period, the central node causes a new wireless communication path to be determined for the communication node, wherein, for the first communication node, when the central node does not receive an indication that the first communication node has performed a network transmission within a second threshold time period, the central node causes a new wireless communication path to be determined for the first communication node, and wherein the first threshold time period is shorter than the second threshold time period.
