Simnet2cir

class pylayers.exploit.simnet.Simnet2cir(simnetfile='pyray.ini')

Bases: object

This class allows to perform a raytracing simulation from a simulnet simulation. First of using it, you MUST have run a simulnet simulation.

1) From your Project directory, configure simulnet.ini save section with: Save =[‘pyray’]

2. Run simulnet

from pylayers.simul.simulnet import * S = Simul() S.runsimul()

3) At the end of the simulnet simulation, a ‘netsave’ folder has been created into your Pylayers project directory. This folder contains all required files for Simnet2cir computation

4) Launch the Raytracing simulation from the pre-computed simulnet simulation:

from pylayers.exploit.simnet import * E = Simnet2cir() E.compute() #

5. See CIR results using pltciri or pltcir:

>>> E.pltcir(1,2,1)
>>> E.pltciri(1,2)

Methods Summary

compute()	Compute Raytracing simulation with the given simulation files
load()	Load simulnet_data configuration file
on_key(event)	Events on key stroke
onclick(event)	Events on click
pltcir(itx, irx, pn[, fig])	Plot channel impulse response for Tx,Rx and a specified position Parameters ———- itx : int node number irx : int node number pn : int position index of the Rx
pltciri(itx, irx)	Plot channel impulse response interactiveley.
srchpoint(x, y)	Search from the closest point (x,y) into self.tx.position and self.rx.position

Methods Documentation

compute()

Compute Raytracing simulation with the given simulation files

load()

Load simulnet_data configuration file

on_key(event)

Events on key stroke

onclick(event)

Events on click

pltcir(itx, irx, pn, fig=[])

Plot channel impulse response for Tx,Rx and a specified position Parameters ———-

itxint

node number

irxint

node number

pnint

position index of the Rx

pltciri(itx, irx)

Plot channel impulse response interactiveley. diplay all node position of Tx and Rx and chose for which link you display the CIR.

Once you have call self.pltciri(node1,node2) 1) Press ‘t’ on the displayed graph to chose the Tx 2) Press ‘x’ on the displayed graph to chose the Rx 3) Press Enter to display CIR betwen Tx-Rx

itxint

node number

irxint

node number

usage

>>> W = W2()
>>> W.pltciri(6,1)

srchpoint(x, y)

Search from the closest point (x,y) into self.tx.position and self.rx.position

x : y :

Nint

node ID

posint

index of the closest position
