WSageNt: Multiagent Platform for Wireless Sensor Networks

The WSageNt platform is capable to run agents in wireless sensor nodes - specificly MICAz and IRIS motes. Software is divided to two main parts - agent platform and interpreter of ALLL language (Agent Low Level Language).

The WSageNt core platform is programmed in TinyOS (version 2). Such platform can be run in TOSSIM simulation tool, so you can easily test basic agents via simulation scripts. This way of working with WSageNt is reccomended if you don't have motes fysicaly. We also provide supporting applications that are written in Java language and their main purpose is to send/recieve messages (and agents) to/from Wireless Sensor Network (WSN). All software that we offer on this page is under BDS license (see Licence section for more information).

Key features of WSageNt platform are:

  • Load/unload agent from/to mote (agent mobility).
  • Send/receive messages (communication of agents).
  • Interpret agent code written in ALLL language.
  • Written in TinyOS v2 (better compatibility to the future).
  • Open source and able to run in TOSSIM simulator.

Installation

The WSageNt is divided into separate packages. First one contains core WSageNt platform which is loaded to real motes or can be run in TOSSIM simulator. Second part is named Control Panel and it is supporting application that is able to send/ receive agents to/from WSN network.

Installation - core

Requirements
  • TinyOS 2.1.1
  • MICAz or IRIS motes (to deploy physicaly)
  • (optional for testing) Python 2.6 (or higher)
Downloads

WSageNt source code
ZIP download wsnagent(TOS=2.1.1).tar.gz
 
Copy of BaseStation source code (Intel license)
TGZ download BaseStation.zip

Installation guide
Download and unpack WSageNt sourcecode. Compile and load our platform to mote:
make micaz install,2 mib520,/dev/ttyUSB0
NOTE: We suppose MICAz platform, ID of mote is 2 and we are using mib520 programmer located in /dev/ttyUSB0 - change acordingly to your needs.




Use BaseStation application located in you TinyOS/apps installation directory. We have also placed a copy of this application on our page. Compile and load to mote ID 1:

make micaz install,1 mib520,/dev/ttyUSB0
NOTE: Basesttation should have always ID = 1. It will be usefull to other software parts that we provide.

Testing using TOSSIM

Locate file src/interpret/AgentC.nc and modify event ControlI.booted(). You can add strings to plan part (stack) using Zasobnik.push_str, to register and planbase using Tabulka.add_str methods.

Example:
  event void ControlI.booted() {
    char c[200];
    dbg_clear("Boot", "Boot: Mote booted at %s\n",sim_time_string());
    call PoleCntrl.start();

    if (TOS_NODE_ID == 1) {
      strcpy(c, "!(2,(asd))");
    }
    if (TOS_NODE_ID == 2) {
      strcpy(c, "$(l,(r,0))$(s)$(l,(r,1))");
    }

    call Zasobnik.push_str(c, (uint16_t)strlen(c));

    call ControlI.run();
  }
Compile in simulation mode:
make micaz sim
Modify src/test.py script (add or remove some node) and run it.

Installation - Control Panel and BSComm

Control Pnel is a Tomcat application that can send/recieve agents to/from WSN network through your web browser. It uses supporting low layer application BSComm, which what it can communicate through socket. BSComm is used there for storing messages from/to network in queue and for establishing communication protocol used in our core platform.

Requirements
  • Mysql 5
  • Java 1.6 (or higher)
  • Netbeans 6.7 (or higher)
  • hibernate-support library
  • ejb3-persistence library
  • mysql-connector library
  • TinyOS .jar file
  • Tomcat 6
  • Apache 2
  • Struts 2
  • Basestation programmed and connected to /dev/ttyUSB0
Downloads

BSComm source code
ZIP download BSComm.zip
 
Control Panel source code
TGZ download ControlPanel.zip

Installation guide

Create database named "wsagent" and username "wsagent" with rigts to acces this database. Password should be "hesloveslo".

Download and unpack BSComm and ControlPanel source code.

Open in Netbeans project BSComm and correct paths to libraries depending on your system. Change username and password to your database in your hibernate options (hibernate.cfg.xml file). Do the same for ControlPanel.

Build BSComm project and run jar file:
java -jar BSComm.jar serial@/dev/ttyUSB1:iris 7777
NOTE: We suppose IRIS platform basestation with communication port at /dev/ttyUSB1. Socket for communicating with control panel will be at 7777 port - change acordingly to your needs.

Install tomcat, create user with admin and manager privileges. For Ubuntu systems should be in /var/lib/tomcat6/conf/tomcat-users.xml file something like this:

<tomcat-users>
  <role rolename="manager"/>
  <role rolename="admin"/>
  <user username="magik" password="makej" roles="admin,manager"/>
</tomcat-users>

Permit operation with database for Tomcat. This file will grant all permissions. Put it into config directory (/var/lib/tomcat6/conf/policy.d in Ubuntu).

Open your web browser and go to "localhost:8080". Start manager and login with user that is able to administrate projects (magik from an example). Deploy ControlPanel.war file with modified connection settings to your database (file hibernate.cfg.xml).

Start and open web page with Control Panel, it should run now:-)
