The simulation of mobile networks relies on a reliable movement generation.
Random movement patterns are frequently used in simulators. In this report,
the performance of the popular setdest movement generator, which is built
into the ns2 open source simulator, is investigated using two statistical tests:
quadrat count test and the variance to mean ratio (VMR) test. The results
show a non-uniform distribution of nodes during the simulation with a bias
towards placing the nodes in the center of the simulated area. We propose
and implement a different method for random movement generation in the
ns2 simulator and show that our movement generator improves the randomness
of the node distribution during the simulation. The new generator was
successfully tested with the ns2 simulator.
