  own, individual power management policies.
  
+ TinyOS 2.0 provides low-power stacks for the CC1000 (mica2)
+ and CC2420 (micaz, telosb, imote2) radios. Both use a low-power
+ listening apporach, where transmitters send long preambles or
+ repeatedly send packets and receivers wake up periodically to 
+ sense the channel to hear if there is a packet being 
+ transmitted. The low-power stack CC1000 is standard, while
+ the CC2420 stack is experimental. That is, the default CC1000
+ stack (chips/cc1000) has low-power-listening, while the default 
+ CC2420 stack (chips/cc2420) does not. To use the low-power CC2420
+ stack, you must include chips/cc2420_lpl in your application Makefile.

--- 352,359 ----
  collection builds a routing tree rooted at a sink node. Together,
  these two protocols enable a wide range of data collection
! applications. Collection has advanced significantly since the
! most recent beta release; experimental tests in multiple 
! network conditions have seen very high (>98%) deliver rates
! as long as the network is not saturated.
