MobilityXYExtractionB

Extract the coordinates of network nodes from a graphic window when n moving nodes are defined after nf fixed nodes for a VANET.

Calling Sequence

[nodex,nodey]=MobilityXYExtractionB(f,n,nf)

Parameters

f :

graphic window ID.

n :

quantity of moving nodes

nf :

quantity of fixed nodes.

nodex :

nodes x-coordinates

nodey :

nodes y-coordinates

Description

MobilityXYExtractionB extracts the coordinates of network nodes (nodex,nodey) from a graphic window when n moving nodes are defined after nf fixed nodes. It is used for the VANET scenario when roads are defined before nodes.
