I-LENSE Topology Generator (topo_gen)

Topo_gen is a handy way to generate sensor network topologies with random node placement for sensor network simulation experiments. Topo_gen will generate either EmSim ".sim" files or ns2 topology files. Topo_gen has numerous configurable parameters such as: x and y dimensions, node count , source and sink count, clustered or random source and sink placement, optional diagonally opposite source and sink placement for maximum hop count, and radio power. Topo-gen is perfect for experiments that require multiple random node placements. Although it was originally developed for use in experiments with directed diffusion, it is easily modified to support other protocols. For EmSim usage, just put the desired modules into your ".tab" files. For ns-2 you must modify the code in the "printTrafficFile" routine to refer to your protocol (lines 644-648, 661-665, 730-736, 748-757). Future versions of topo_gen will include support for a virtual print routine that can be supplied by user created sub-classes.
