An integrated data-link energy model for wireless sensor networks

In this paper we integrate the energy models of all the components of the data link layer of a wireless sensor network into a single framework, which interacts with the abstracted models of the network layer, the physical layer, and the channel. Such a framework enables intra layer and cross layer optimization. By identifying the important design parameters, it provides the venues and guidelines for energy´ reduction and design improvement, as demonstrated in the paper. The validity of the models is verified using OMNET++ network simulations.
