Abstract
Official abstract text for this publication.
Methods and systems for preserving the life of a power source of a wireless end node of a wireless communication system for use in a mobile environment are provided. In one embodiment, a method is provided that includes wirelessly transmitting a wireless end node acknowledgment message to a network coordinator during a normal operation mode of the wireless end node. The method also includes the wireless end node monitoring for a network coordinator acknowledgment message from a network coordinator in response to the wireless end node acknowledgement message during the normal operation mode of the wireless end node. Also, the method includes incrementing a missed acknowledgment counter value stored in a memory storage of the wireless end node when the network coordinator acknowledgment message is not received. Further, the method includes increasing a time period of a sleep timer of the wireless end node when the missed acknowledgment counter value equals a missed acknowledgment threshold.
