INNOVATIVE MONITORING SYSTEMS AND PROTOCOLS FOR WIRELESS NETWORKS AND WIRELESS SENSOR NETWORKS

Computer networks have been used in everyday life for a long time, but recently, the majority of the IOT projects needs network appliances to support network integrated monitoring systems. In this thesis the focus is on monitoring systems that were applied to a network designed and managed by the iXem labs of Polytechnic of Turin. This network is made up of 2000 routers, almost half wired and half wireless, with different capabilities and from different brands. Before the current thesis, they were all managed by means of a proprietary monitoring system. The fundamental aim of the thesis is the improvement of the monitoring system to support further scales-up of the iXem network. Initially, a cloud virtual experiment has been run in a smaller portion of the network, using Zabbix. To check Zabbix performance in analysis and prediction and the most important factors, using automated steps along the way to scale down the average time of each part. Hence it was applied to other parts of the network in the Piedmont region and the entire network was converted to Zabbix. The first activity was the activation of the most effective and operational protocols on each device, in order to automate the Zabbix implementation. The second major activity was to build a suitable interactive map in order to visualize devices on a network, their inter-relationships and the transport layers providing network services. In conclusion, I moved all the networks to a new, open source, free and easy to use monitoring system. Thanks to the automated process that was realized, now any migration process, including the addition of all devices and the creation of the related map, could be almost immediate. The new system helps network managers to evaluate potential solutions, to solve problems and predict the incoming issues in a shorter amount of time compared to the past.
