- 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
