Abstract

A basic problem introduced by the use of radio duty cycles asand energy saving technique is the need to establish rendezvousbetween transmitter and recevier. 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 trasnmitter-receiverrendezvous.The benefits of applying framelets is assessedanalytically and an implementation of the concept fro the DSYS25 sensor platform is presented and evaluated. The results show that subtantial energy savings can be achieved with framelets as well as an increase in communicationthrougput.
