-1. SETTING UP THE TEST
-
-You need to first generate the code for compilation. The gentest.py
-script reads in the Master files and creates TestDIPC.nc (the
-configuration) and TESTDIPP.nc (the module). It takes two parameters,
-the total number of items and the number of new items. The items that
-are random are chosen randomly.
-
-If you want 128 total items in the dissemination set, where 96 of
-those 128 items are new, you would type:
-
-python gentest.py 128 96
-
-After the configuration and module have been generated, you can use
-the normal compilation method (e.g. make telosb).
-
-2, READING THE LEDS
-
-When an node receives a new item, it toggles LED0. When a node
-completes all items, it turns all LEDs on.
-
-3. SERIAL MESSAGES
-
-typedef nx_struct dip_test_msg_t {
- nx_am_addr_t id;
- nx_uint8_t count;
- nx_uint8_t isOk;
-} dip_test_msg_t;
-
-When a node receives a new item, it sends a dip_test_msg_t through the
-serial interface.
-
-id is the node id
-count is how many new items it has received so far
-isOk will be true if the data value was as expected
-
-4. PACKET INJECTOR
-
-You can also use the injector to send data packets via a
-basestation. The syntax to do that is:
-
-java DipInject [key] [version] [data in quotes delimited by space]
-
-key is the data key in hexadecimal
-version is the version number in decimal
-data is the actual data in quotes delimited by space
-
-For example, if you want to send key 10, version 2, and data "ab cd
-ef". You would type:
-
-java DipInject 0a 2 "ab cd ef"
-
-For this specific test application, your data needs to be "ef be". You
-will need a SerialForwarder running for this work.
-
-5. TIMING
-
-With a single sender and single receiver on a table using TelosB
-nodes, it takes approximately:
-
-3.5 minutes for a node to receive 128 out of 128 items.
-4.0 minutes for a node to receive 240 out of 240 items.
-
-With a single sender and two receivers on Mirage MicaZ nodes, it takes
-approximately:
-
-2 minutes for both nodes to receive 96 out of 96 items.
-With 128 items or more, MicaZ nodes don't receive anything. Memory limitation?
