- OMG TRACE support mobility input given in the following format:
- TIME(s) NODE_ID NODE_POS_X NODE_POS_Y NODE_SPEED(m/s)
+ EXPECTED_TIME(s) NODE_ID NODE_POS_X NODE_POS_Y NODE_SPEED(m/s)
- Note: OMG uses the speed (NODE_SPEED) at this time (TIME) from this position (NODE_POS_X,NODE_POS_Y) for this NODE_ID
- - each input may be ordered (in time) or not
-
- - The mobility described in the mobility file strictly follows the simulation time, only condition where it doesn't follow is, when a node fails to reach its next point (in time) from where it has to start next journey.
+ Notes:
+ 1) OMG uses the speed (NODE_SPEED) at this time (TIME) from this position (NODE_POS_X,NODE_POS_Y) for this NODE_ID
+ 2) each input may be ordered (in time) or not
+ 3) early arrivals at each points cause a sleep for a duration of the time difference
+ 4) late arrivals for each points cause nothing (no jump), the point will be reached later in time.
+ 5) all the points will be reached based on their expected times.
+ 6) if the first expected time is greater than zero, then the node will be in a pause state at the initial position for the duration of the expected time
+ 7) The mobility described in the mobility file strictly follows the simulation time, only condition where it doesn't follow is, when a node fails to reach its next point (in time) from where it has to start next journey.
+ 8) the speed for the last expected time is ignored
