Is Wilab something for you?

Running applications on Wilab

Available Real-time applications without login visualisation of the temperature on a map

Select [w-iLab_t]_Visual_Temperature Click on the button ”start visualiser”

Use keyboard arrows to zoom Enter A to add and R to remove the time slider

Running applications on Wilab

Available real-time applications without login Temperature graph of one node

Still in the toolbox Select [w-iLab_t]_Analyse_Temperature Click on the button ”start analyser”

Double-click to store the graph in your home directory

Cycle 5 min Inode → EE → DUT (Power for 10s) DUT runs default firmware

Transmits over USB a packet with temperature,… Inode forwards the packet to wilab.test Wilab.test adds extra info

OS and Software

Software Sensornode : Tinyos

Why tinyos Big community, support for many platforms, huge

implementation resource,... one IBBT team = one development environment

General description on en.wikipedia.org Tutorials on http://docs.tinyos.net/index.php/ IBBT Subversion https://svn.atlantis.ugent.be/svn/wsn/

IDRA framework (contact Eli De Poorter) Network and cross layer architecture

iNode OS and software

Debian 5.0 (Lenny) Voyage distro 0.6.1 Patched kernel 2.6.24.7 for click Click modular router 1.6.0 with all elements available in

user level and as kernel module JRE 1.6.0_12 Time synchronization via ptpd IEEE 1588 standard

wilab.test synchronized with ntp.atlantis.ugent.beptp master clock

Convergence (offset from master)< 100 us after ca. 8 min< 10 us after ca. 13 min

Preparing Software for the iNode

Best practice: prepared VM (http://wilab.test/data/wilabuser) Desktop iNode

Apt-get install’s are not recommended Copy binaries instead (check with file arch <=i586) Locate the libs you need with ldd Execute with:

LD_LIBRARY_PATH=~/iPlatform/libs click

How to put applications on wilab?

An account on wilab

New accounts: Account features:

Quota in minutes per half floor (smallest zone) Database (remote access + phpmyadmin) Ssh account on wilabfs (shared 1.5TB) Ssh account on the iNodes

Personal IP is used in dynamic firewall More info, changing password or IP on:

Wilab policy and sandbox

No WiFi experiments between 06:00 and 22:00 Enforcement

Experiments can always be scheduled Wireless interfaces are continously monitored and

killed When killed, message is written to the log files

Sandbox No enforcement

p. 30

Experiments on wilab are JOBS

Registering messages

enum { AM_TEMPHUMLIGHTMSG = C};

typedef nx_struct { nx_uint16_t temperature; nx_uint16_t humidity; nx_uint16_t light;} TempHumLightMsg;

TempHumLightMsg.java

javac

TempHumLightMsg.class

Add java class to job A Schedule ID = B

Automatically a table A_B_C will be created

with the same fields + locationID + timestamp

Job

Job contains: Tinyos firmware images Registered messages Scenarios

Execute events on predefined relative times (or RT) iPlatform = wilabfs.test/home/user/iPlatform/iNodeProfile

Contains bins, scripts, libs, config Start_mount_script will be started after boot Specific kernel /tmp/log is mounted to ./log/ScheduleID/NodeID/

Schedule a Job in a wilab zone in a free time slot Analyze your messages in the db RT or offline with

easy to configure via xml (some examples on the server) wilab-visualiser wilab-analyser

Sample Experiments

Sample sensor experiment

Example research application: RadioPerf (IBCN devel.) Configurable packet generator

Radio (txPower, channel)Packet generator (#, size, IPDelay,…)MAC properties (backoff, retries,…)LPL properties (duty cycle,…)Reports (IRDelay, …)

Dumps reports every IRDelayEnf, #Tx, #Rec, RSSI, LQI,…

Result 1 Experiment transmitters on 2nd floor

Result 2 Experiment transmitters on 2nd floor

Result 3 Current measurements during Tx with Lpl

Experiment iPlatform (dist. ca 30m)

Max throughput on Turbo Channel without tweaking the Qos parameters using 1 wireless interface per iNode:

^AP / Wireless terminal ->

Unicast UDP:Ca. 65 Mbits guaranteedOn channel 50 (a band)

Tweaking QoS WiFi parameter can give a profit of 10%
