Comparative study for identi cation of multiple alarms in telecommunicationnetworks

Abstract

Telecommunication networks consist of communication units interconnected physically or by means ofprotocols in order to provide basic services like data, voice, or image transfers. In this study, a modeling frame fornetwork units and their links in a topological frame is presented based on a real mobile communication network namedTASMUS (TAktik Saha MUharebe Sistemi - Tactical Field Combat System). Alarm handling is one of the most criticalfeatures required in communication networks. Based on simulated single alarm and multiple (double) alarm scenarios,known powerful alarm estimation approaches, namely the coding method, neural networks, and knowledge-based systems,have been studied to assess their capabilities for identifying multiple faults that might occur simultaneously in real time.They have also been compared in order to evaluate the performance of alarms under different noise levels for speci cTASMUS networks.
