Monitoring of a DTN2 network

In this paper we point out the necessity for monitoring the status of a Delay-Tolerant Network (DTN) and present the network monitoring functionalities we implemented in a small network comprising of three nodes based on the DTN2 implementation of the DTN Bundle protocol. The methods used to gather the appropriate statistics are described and the key parameters needed to describe the DTN network status are analyzed and assessed regarding their efficiency to monitor networks performance.
