Abstract :
Cross-layer models are becoming popular in various wireless networking domains due to their realistic predictions and for fundamental understanding of the interaction between adjacent networking layers. A combined PHY/MAC layer energy consumption model is considered here for short range IEEE 802.15.4 networks for non-beacon-enable mode in case of dual hop transmission under Rayleigh fading channel. For both AF and DF relays this cross layer model is developed and a comparison of energy efficiency is done for this two type of relays. In particular, we focus on how the new model differs from single-layer models (either PHY or MAC) in terms of energy efficiency.
