Taxonomy of Security Protocols ◾ 315
As in the case of TinySec packets, LLSP message headers travel unencrypted,
enabling the implementation of early rejection techniques. In this way, it is possible
to save energy, just making the sensors switch off the radio transceiver when they
detect that they are not the destination of the received message. e same happens
with the MAC. As it is not encrypted, a receiver can check the authenticity of a
message with low energy consumption.
12.2.3.3 Performance Analysis
e developers of LLSP use the PowerTOSSIM simulation environment to

Mica2 sensor node. ...
