Mobile Agents to Automate Fault Management in Wireless and Mobile Networks

Abstract

Abstract. This paper studies the automation of fault management of wireless and mobile networks. A network management protocol similar to SNMP with an integrated architecture using mobile agents will prove effective in fault management of such networks. In view of the above, we design a wireless network management protocol to support fault management. In particular, we use mobile agents to detect, diagnose and recover from faults in wireless and mobile networks.

Analysis of mobile agents in network fault management

“…Fault management includes the discovery, isolation and fixing of problems, the efficiency of fault management is crucial to guarantee the recovery of faults that may occur during the network life cycle. In previous research (Wittner et al, 2000;Hood and Ji, 1997;Pissinov et al, 2000;Li and Baras, 2000;Gurer et al, 1996;Goldszmidt, 1996;Gavalas et al, 2000) in network fault management (NFM), the scalability limitations of centralised network management (NM) is addressed and it becomes significantly more pronounced when transfers of bulk network monitoring data is considered.…”

Network fault detection with Wiener filter-based agent

“…In previous researches (Wittner et al, 2000;Hood and Ji, 1997a;Pissinov et al, 2000;Li and Baras, 2000;Gurer et al, 1996;Goldszmidt, 1996;Gavalas et al, 2000) in network fault management (NFM), the scalability limitations of centralised network management (NM) are addressed and it becomes significantly apparent when transfers of bulk network monitoring data are considered. To overcome these limitations, these researchers have adopted many techniques in the area of artificial intelligence and statistics of such expert systems (Jakobson and Weissman, 1993), finite state machines (Rouvellou, 1993), advanced database techniques (Wolfson et al, 1991) and probabilistic approaches (Deng et al, 1997).…”

Automating Cellular Network Faults Prediction Using Mobile Intelligent Agents

“…While these works explored ways of applying intelligent agents and Bayesian Belief Network (BNN) in network faults prediction, they did not address the relationship between cellular network faults and service provision, and only explored the network layer. Pissinou et al [11] apply mobile agents to automate the fault management in wireless and mobile networks. While this work delves into detection of faults and automated recovery from faults, it does not deal with reporting such faults before they occur.…”
