JBotSim is a multipurpose dynamic network simulator that allows to quickly prototype a distributed algorithm and test its behavior on a set of static or mobile nodes. If mobile, the nodes can be controlled by the mouse or by program.
Evolving Realistic Topologies for Wireless Network Simulation
...The softare evoTopo is able to generate multiple different topologies based on a given reference example, typically from a real-world setup. Based on this an evolutionary algorithm evolves new topology files with equal parameters regarding node density, distribution homogeneity and network properties such as node degree distrbution.
evoTopo can be used with any wireless network simulator that will accept a node position file of some form. The reference file must be given in .csv format listing the x- and y-coordinates of the nodes. evoTopo is written in Java and will run on Java 6 or higher. ...
