1. A method for assigning a local constraint to a remote site in a network, the method comprising:
- generating, by a central controller, the local constraint for the remote site based on probabilities and system costs associated with a local alarm transmission by the remote site and a global poll in the network, the local constraint being generated in response to an update message received from at least one remote site in the network;
assigning the local constraint to the remote site.

Abstract
Methods for tracking anomalous behavior in a network referred to as non-zero slack schemes are provided. The non-zero slack schemes reduce the number of communication messages in the network necessary to monitor emerging large-scale, distributed systems using distributed computation algorithms by generating more optimal local constraints for each remote site in the system.

9. A method for generating a local network constraint value for a remote site in the network, the method comprising:
-
estimating, locally at the remote site, a total system cost based on probabilities and system costs associated with a local alarm and global polling of remote sites in the network; and generating a local constraint based on the estimated total system cost such that the local constraint value is less than a maximum local constraint value, the maximum local constraint value being determined based on a number of nodes in the network and a global constraint for the network. - View Dependent Claims (10, 11, 12, 13)

14. A method for adaptively assigning a local constraint to a remote site in a network, the method comprising:
-
generating a local constraint based on an estimated total system cost, the estimated total system cost being indicative of costs associated with local alarm transmissions and global polling of the network; approximating a probability of a global poll in the network based on a sum of expected system cost contributions of the remote site and the generated global constraint; and probabilistically adjusting a local constraint value at the remote site in the network by a first factor in response to a local alarm or global poll event in the system. - View Dependent Claims (15, 16, 17, 18)
