Flooding-Based Network Monitoring for Mobile Wireless Networks

—The monitoring and online analysis of computer networks is a wide field of research, covering many applications from constant load determination of high-performance wired networks to connection-oriented measurements in different QoS applications. QoS-enabled routing in mobile ad-hoc networks (MANETs) is the most common application for network monitoring in dynamic wireless network topologies. We describe three example applications requiring the monitoring of connection reliability, transmission delay and the network topology. The presented set of applications shows similarities in the used communication network. A network monitoring system used in such network has to have specific properties. We surveyed a number of existing protocols and propose an additional system for network monitoring in mobile wireless networks. We implement and test a Flooding-Based Network Monitoring (FBNM). The impact of flooding-based systems on primary communication using the same wireless medium is tested using the implemented system. The delay of message transmission multi-hop networks is analyzed.
