Testbed at the University of Lübeck

The local testbed at the University of Lübeck is located in the office room at the Institute of Telematics (Building 64, 2nd floor).

Testbed Description

The WISEBED compatible testbed consists of 162 nodes of three different kinds (iSense, TelosB and Pacemate) in 15 rooms and the sandbox of 18 nodes in one isolated room.

The nodes are arranged in clusters and each cluster has one sensor node of each node type. There are two different cluster layouts in the UZL testbed, which differ in the sensor module connected to the iSense node. Half of the iSense sensor nodes are equipped with an environmental sensor module (measuring temperature and light sensor) while the remaining nodes are equipped with a security module (featuring a passive infrared sensor and an accelerometer). This setup allows us to compare and benchmark the same algorithm or application on different hardware with nearly identical conditions and even in heterogeneous testbeds.

The clusters are connected to a total of 20 Acer Aspire One netbooks forming the backbone of the testbed connected to the Internet. The sensor nodes are connected to the netbooks via USB and the netbooks itself are connected to the Internet via a Fast-Ethernet LAN connection. This backbone enables the user to program or reset the sensor nodes without the need of an additional OTAP (Over the air programming) protocol. Furthermore it is used to debug the testbed, capture trace files and deliver data via virtual links without influencing the sensor node radio channel.

The UZL testbed consists of the following sensor nodes:

  • iSense by coalesenses
    • Jennic 32 bit microprocessor (JN5139R1 / JN5148)
    • 802.15.4 radio interface
    • Fixed Power Supply via USB Interface
    • Half of the nodes are equipped with temperature and light sensors
    • the other half with a PIR and an accelerometer
  • TelosB by Crossbow (now willow)
    • Texas Instruments 16 bit microprocessor (TI MSP 430)
    • 802.15.4 radio interface
    • Fixed Power Supply via the USB Interface
    • Temperature, humidity and light sensor
    • 1 MB external flash
  • Pacemate designs by the ITM
    • Philipps 32 bit microprocessor (LPC 2136)
    • Radio interface at 800 MHz
    • Display and three buttons

Address Spaces

Every node type has a designated address space so you can tell from the MAC address of which type the node is and to which gateway it is attached.

Node TypeSmallest AddressLargest Address
iSense Jennic JN5139R10x20000x20FF
iSense Jennic JN51480x21000x21FF
Telos B0x22000x22FF
Pacemate0x23000x23FF

Every room contains one or two gateways. Three boxes are attached to every gateway. Every box contains three nodes of which one is a Telos B mote, one a Pacemate node and one is an iSense node. Depending on the actual box it may be either an iSense node of the old generation (using a JN5139R1 CPU) or one of the new generation (using a JN5148 CPU).

For every gateway a total number of 16 addresses is reserved, 4 per node type and not all of these addresses are currently in use (check the large-scale plan for details).
