Abstract

A basic problem introduced by the use of radio duty cycles as an energy saving technique is the need to establish rendezvous between transmitter and receiver.Since communication can only take place when the receiver s radio is active, the transmission of frames needs to somehow overlap with this active period. This paper investigates the use of framelets - small, fixed-sized frames - to achieve transmitter-receiver rendezvous and contrasts this technique with the use of long frames. The benefits of applying framelets is assessed analytically and an implementation of the concept for the DSYS25 sensor platform is presented and evaluated. The results show that substantial energy savings can be achieved with framelets as well as an increase in communication throughput.
