An alternative simulation environment
A new version of NesCT + OMNeT++ simulation environment is now available. OMNeT++ has a good GUI support, you can slow down or increase the speed of simulation at runtime. Even you can run your simulation until an event occurs or until some simulation time. This is very handy while debugging. You can see the overall view of the network, while the messages are being transmitted. With this, you get better grip of what you are doing. OMNeT++ is faster than TOSSIM, you may run your simulations for hours instead of minutes. You can mix different applications into same simulation. While one node may run CntToLedsAndRfm, the other may run TOSBase,RfmToLeds or Surge. Assumption of a homogoneous network is dangerous for real life applications. With the integration of MF (Mobility framework), you can run your simulations on a mobile testbed. You can assign some of the nodes to have mobility using a mobility model from various flavors. MF incorporates more accurate physical layer than TOSSIM. However, the radio included is an 802.11 radio. You can tune the parameters such as transmission range, speed, delay etc. so that it can model your existing WSN radio.
