HowTo/virtualMobility

@@ -8 +8 @@
 The method described here is a third way. It is implemented as a modification to the madwifi driver. Basically what it does is allows incoming packets to be filtered by sending MAC address. These filtered packets can have an arbitrary RSSI assigned to them and an arbitrary percent of these incoming packets can be ignored in order to simulate a poor radio environment.
 
+What this tool can do:
+ 
+ * Simulate any arbitrary topology, including one-way links
+ * Support any number of nodes moving in a virtual 3d space
+ * Allows on-the-fly adjustment to any topology in real-time
+
 A few things to remember:
 
  * Since this modification is at a very low layer in the madwifi driver (just after the HAL), it is completely transparent to all routing and packet shifting performed by both the kernel and userspace applications.
  * Packet skipping occurs above the HAL, so multiple hardware retries, etc have no effect on packet receive percentages.
- * When using this tool packets are still sent and received at the hardware layer, and thus you will still need to be sure you're not saturating your radio environment even if you're nodes don't seem to be receiving packets.
