Abstract
In this paper, we propose a new scheme that allows coupling beacon-enabled
IEEE 802.15.4 with the RPL routing protocol while keeping full compliance with
both standards. We provide a means for RPL to pass the routing information to
Layer 2 before the 802.15.4 topology is created by encapsulating RPL DIO
messages in beacon frames. The scheme takes advantage of 802.15.4 command
frames to solicit RPL DIO messages. The effect of the command frames is to
reset the Trickle timer that governs sending DIO messages. We provide a
detailed analysis of the overhead incurred by the proposed scheme to understand
topology construction costs. We have evaluated the scheme using Contiki and the
instruction-level Cooja simulator and compared our results against the most
common scheme used for dissemination of the upper-layer information in
beacon-enabled PANs. The results show energy savings during the topology
construction phase and in the steady state.
