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 Type||Smallest Address||Largest Address|
|iSense Jennic JN5139R1||0x2000||0x20FF|
|iSense Jennic JN5148||0x2100||0x21FF|
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).
The local WISEBED testbed at the University of Lübeck is located in the office room at the Institute of Telematics (Building 64, 2nd floor). The 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 theremaining 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:
Two UZL clusters connected to an Acer Aspire One as backbone in the ITM seminar room.
UZL cluster with an iSense, Pacemate and TesloB mote.
The two cluster layouts with different sensor modules (Environmental and Security module).
