MobilityXYExtraction

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

Calling Sequence

[nodex,nodey]=MobilityXYExtraction(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

MobilityXYExtraction extracts the coordinates of network nodes (nodex,nodey) from a graphic window when n moving nodes are defined after nf fixed nodes.

Examples

scf(1);//creation of a graphic window
clf(1);
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]=MobilityRandom_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
MobilityGraph2Plot(nodex(nf+1:$),nodey(nf+1:$),r,5);//fixed nodes in red (5)
MobilityGraph2Plot(nodex(1:nf),nodey(1:nf),rf,2);//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($-1).children(n-i+1).background=6;//node i
show_pixmap();//display
[nodx1,nody1]=MobilityXYExtraction(f,n,nf);//application of MobilityXYExtraction
Tnodes=zeros(1,n);//initialization of breaking time parameters
Tmax=100;//maximal waiting time
dmax=180;//Locality radius for the links attribution
he=[];//link head vector
ta=[];//link tail vector 
col=[3 5 2];
cb=1;
//displacement of nodes 
for i=1:n
fr=f.children.children($-1).children(n-i+1);//node i 
[fr.data(1) fr.data(2) destx(i) desty(i) d(i) v(i) Tnodes(i)]=MobilityNodeRWP(fr.data(1),fr.data(2),destx(i),desty(i),d(i),v(i),Tnodes(i),Tmax,vm,L);
//displacement of the node i			
end
[nodx2,nody2]=MobilityXYExtraction(f,n,nf);//application of MobilityXYExtraction
