This paper presents our ongoing works towards visual exploration of large network simulation outputs. Visual exploration allows users to search through simulation traces by using multidimensional representations of the network in an intuitive and interactive way. To speed up trace file exploration, we propose to store the simulation events according a format, namely XAV, that i) exploits the multidimensional nature of users requests and ii) allows quick identification of the packet paths through the network. XAV files are stored in a database to simplify data manipulation. The XAV tracing framework has been implemented in the NS-2 simulator and tested over a wireless ad-hoc network composed of 25 nodes. The performance evaluation shows that XAV enables to extract about 1000 packet paths per second from 100 MB trace files.
