NARVAL_M_Graph2Plot

Display a graph with mobile nodes on a normal figure.

Calling Sequence

[f] = NARVAL_M_Graph2Plot(x,y,r,c,w)

Parameters

x :

x-coordinates vector.

y :

y-coordinates vector.

r :

node radius used for the display.

c :

node color used for the display.

w :

window index.

f :

handle of the graph window.

Description

NARVAL_M_Graph2Plot displays the animated network graph g composed by mobile nodes on the window of index w defined by its handle f. Network nodes coordinates x and y are assumed to be known.

Examples

w=1;//window index
scf(w);//creation of a graphic window
clf(w);
f=gcf();
f.figure_name='MANET';
f.pixmap='on'; //set the pixmap mode
//creation of the network boundaries
plot2d(0,0,-1,"011"," ",style=5,rect=[0,0,1000,1000]);
xgrid;
//simulation scenario
r=10;//display radius of moving nodes
rf=15;//display radius of fixed nodes
rs=20;//display radius of the moving nodes belonging to the connection under studies
n=50;//quantity of moving nodes
nf=5;//quantity of fixed nodes
[ndep,nfin]=NARVAL_M_Random_i_j_nf(n,nf);//connection extremal nodes
L=1000;//network square area side
ts=20;//maximum time break
vm=20;//maximum speed
v=vm*rand(1,n);//velocity
Tlim=1000;//simulation duration
nodex=L*rand(1,n+nf);//current x-coordinate of all nodes
nodey=L*rand(1,n+nf);//current y-coordinate of all nodes
destx=L*rand(1,n+nf);//destination x-coordinate of all nodes(not used for fixed nodes)
desty=L*rand(1,n+nf);//destination y-coordinate of all nodes(not used for fixed nodes)
d=sqrt((nodex-destx).^2+(nodey-desty).^2);//initialization of the distance vector
//display the initial state
NARVAL_M_Graph2Plot(nodex(nf+1:$),nodey(nf+1:$),r,5,w);//application of NARVAL_M_Graph2Plot: mobile nodes in red (5)
NARVAL_M_Graph2Plot(nodex(1:nf),nodey(1:nf),rf,2,w);//application of NARVAL_M_Graph2Plot: fixed nodes in blue (3)
show_pixmap();//display
f=gcf();//get the figure properties
i=ndep-nf;//emission node in purple (6)
f.children.children($-1).children(n-i+1).data(3:4)=[rs rs];//node i
f.children.children($-1).children(n-i+1).foreground=6;//node i 
f.children.children($-1).children(n-i+1).background=6;//node i
i=nfin-nf;//destination node in purple (6)
f.children.children($-1).children(n-i+1).data(3:4)=[rs rs];//node i
f.children.children($-1).children(n-i+1).foreground=6;//node i 
f.children.children($-1).children(n-i+1).background=6;//node i
show_pixmap();//display
f.pixmap='off';
