Abstract
A rate adaptive polling method sensitive to network congestion is used to monitor network resources. Initially, a baseline rate constraint is set based on desirable engineering factors. Unacknowledged polls are retransmitted with timeouts, successively increasing by a factor of 2. During each polling round, the rate is adapted in accordance with congestion feedback and changes in node status such as recently activated or deactivated nodes. Congestion feedback is estimated from a congestion metric computed as the average delay of all active nodes. Depending on the value of the congestion metric corresponding to polling round R,, the minimum rate of polling for round R,is adapted accordingly.
