Significant Changes in TinyOS between v1.1.1 and 1.1.3
Last updated 7 January 2004 |
Note: While minor releases deliver TinyOS additions and improvements to the community more quickly, they do so with less testing. If your environment requires stability, consider using the previous major release (TinyOS 1.1.0) or, at the very least, testing your applications carefully with the new release before migrating wholesale to 1.1.3.
This document outlines the changes that have occured in TinyOS since the last snapshot release (1.1.1) and the current minor release (1.1.3). The major changes in 1.1.3 include the new MAC layer, B-MAC, as well as various bug fixes.
TinyOS 1.1.3 includes B-MAC, a new MAC layer w/ CSMA with collision avoidance, gain control, channel filtering for channel clear decisions; max bw from 42 pckts/sec to 53 pckts/sec, outperforms the 1.1 MAC layer by over 100% (in terms of packet throughput) while achieving 85% channel utilization.
Released simultaneously with TinyDB 1.1.3 is the 1.1.3 minor release of task-tinydb which includes numerous bug fixes and upgrades. For more information on TinyDB, please see documentation in the doc/ directory.
