Title:
 FrameComm: Framelet Based Communication for Wireless Sensor Networks

Abstract:
 Wireless sensor nodes employ a duty cycle to conserve
energy. To implement a duty cycle a sensor node constantly switches
the communication transceiver between listen and sleep state. If a
listen/sleep cycle of the receiver is known a sender can transmit a
trail of identical packets, called framelets, of which the receiver is
guaranteed to receive one. Such framelet based communication
mechanisms are currently used in deployed sensor networks. However,
the used framelet communication mechanisms do not explore the full
potential of this communication mechanism. In this talk I will present
a number of framelet communication enhancements that can be used to
implement features such as priority interrupts, data aggregation and
location estimation within the medium access control protocol.
