This directory contains "TKN15.4", a platform-independent IEEE 802.15.4-2006 MAC implementation. The code is in alpha state, under active development, but most of the functionality described in the standard is implemented (and cursorily tested). The MAC itself is platform-independent, but it requires (1) a suitable radio driver, (2) Alarms/Timers with symbol precision and (3) some "platform glue" code (defining guard times, etc.). Currently the only supported platform is TelosB (however: without additional hardware support on TelosB the timing in beacon-enabled mode is not standard compliant). Status 6/16/08 -------------- missing functionality: - security (not planned) - GTS (not planned) - PAN ID conflict resolution - multiple indirect transmissions to the same destination missing documentation: - overview on the architecture of TKN15.4 - porting TKN15.4 to a new platform - ...
