Abstract

Alarm monitoring networks, like fire alarm systems, usually consist of so called local and global nodes. Local nodes monitor a set of sensors directly connected to them and send status messages to the corresponding global node. These keep track of the network’s and the local nodes´ statuses by checking the incoming status messages. When there is too many local nodes sending all their status information at the same time the network can be overloaded which leads to transmission problems.

Rule-Based Network Management in Alarm Systems

Idea: Dr. Andre Benjamin Bondi, US-Princeton; Dr. Christoph Kuhmuench, US-Princeton

Alarm monitoring networks, like fire alarm systems, usually consist of so called local and global nodes. Local nodes monitor a set of sensors directly connected to them and send status messages to the corresponding global node. These keep track of the network's and the local nodes´ statuses by checking the incoming status messages. When there is too many local nodes sending all their status information at the same time the network can be overloaded which leads to transmission problems.

A novel solution to the problem mentioned above is presented in the following. In order to avoid a network overload in alarm monitoring systems local nodes are supposed to selectively send information of a specific type to a corresponding subset of global nodes. This traffic is based on either static tables or a set of rules that can be varied dynamically according to certain criteria like the generating rate or other computable rules. In effect, the set of global nodes to receive specific types of traffic from local nodes can be varied dynamically according to decisions based on rules stored in a global node. This shifting should be triggered by messages to local nodes.

The proposed solution can advantageously be used to limit the amount...
