This is an update to the Ns2MobilityHelper class included in NS-3 Network Simulator to support 3D movement.
It implements the new statement:
$ns at $time $node setdest x2 y2 z2 speed
so that 3D destinations are allowed.
For reference, the statement originally specified in NS2 trace files are:
$node set X_ x1
$node set Y_ y1
$node set Z_ z1
$ns at $time $node setdest x2 y2 speed
$ns at $time $node set X_ x1
$ns at $time $node set Y_ Y1
$ns at $time $node set Z_ Z1
Simply copy the files ns2-mobility-helper.h and ns2-mobility-helper.cc into the folder:
./src/mobility/helper/ns2MobilityHelper/
This update also fixes a bug (existing at least in ns-3.29), where statements of type $ns at $time $node set ... set the specified node's coordinate during parsing of the ns2 trace file, overriding the initial coordinate set with $node set ..., which could also lead to the node deviating from the expected movement pattern.
