A network of motes programmed with TestFtsp run the - FTSP protocol to time synchronize, and sends to the base station the global - reception timestamps of messages broadcast by a dedicated beacon mote - programmed with RadioCountToLeds. Ideally, the global reception timestamps of - the same RadioCountToLeds message should agree for all TestFtsp motes (with a - small synchronization error). - -------------------------------------------------------------------------------- -SUPPORTED PLATFORMS: --------------------------------------------- - The supported platforms are micaz, telosb and iris. - -------------------------------------------------------------------------------- -STEP BY STEP GUIDE TO RUN OUR TEST SCENARIO: --------------------------------------------- - - program one mote with apps/RadioCountToLeds - - program multiple motes with TestFtsp - - program a mote with apps/BaseStation, leave it on the programming board - - turn on all the motes - - start the FtspDataLogger java application (type "java FtspDataLogger") - -------------------------------------------------------------------------------- -REPORTED DATA: --------------- - The most important reported data is the global time of arrival of the beacons. - The beacon msg arrives to all clients at the same time instant, thus reported - global times should be the same for all clients for the same sequence number. - - Each message contains: - - the time of message reception by the java app [JAVA_TIME] - - the node ID of the mote that is sending this report [NODE_ID] - - the sequence number of the RadioCountToLeds message that is increased - for each new polling msg [SEQ_NUM] - - the global time when the polling message arrived [GLOB_TIME] - - a result_t value indicating if the timestamp is valid [IS_TIME_VALID] - (a result_t of 0 denotes a valid timestamp) - -If the application is running correctly, then the output should show -reports from the different FTSP nodes with valid timestamps and similar -global time values. For example, this is a trace with two FTSP nodes, -with IDs 1 and 5: - -1214516486569 1 10916 433709 0 -1214516486569 5 10916 433709 0 -1214516486809 5 10917 433964 0 -1214516486809 1 10917 433963 0 -1214516487045 5 10918 434210 0 -1214516487053 1 10918 434210 0 -1214516487285 1 10919 434454 0 -1214516487293 5 10919 434455 0 - -One way to test if FTSP is operating correctly is to turn off one of -the FTSP nodes. For a short time, that node's global times will differ -significantly and its valid flag will not be 0. For example, this -is what it looks like when node 1 in the earlier trace is reset: - -1214516490953 5 10934 438208 0 -1214516491201 5 10935 438460 0 -1214516491441 5 10936 438712 0 -1214516491685 5 10937 438964 0 -1214516492169 5 10939 439455 0 -1214516492417 1 10940 243 1 -1214516492421 5 10940 439706 0 -1214516492665 5 10941 439960 0 -1214516492669 1 10941 497 1 -1214516492905 5 10942 440213 0 -... -1214516497541 1 10961 5495 1 -1214516497549 5 10961 444958 0 -1214516497793 1 10962 5747 1 -1214516498025 1 10963 445456 0 -1214516498033 5 10963 445455 0 -1214516498277 5 10964 445705 0 -1214516498285 1 10964 445707 0 -1214516498521 1 10965 445964 0 - -This output is also saved in a file named 'current_timestamp.report'. -'.report' files can be used with the FtspDataAnalyzer.m Matlab -application.
