Abstract: Statistical data delivery where data has to reach a certain fraction of nodes without guaranties about specific nodes is a useful communication task in sensor networks. The nature of this task can allow us to be more flexible and adopt a truly cross-layered approach that can provide energy benefits. We consider many local communication parameters and try to jointly optimize them to meet our performance criteria with the least amount of spent energy. Many of these parameters have been considered before in isolation or in small groups by a variety of protocols in diverse networking layers, but not all of them were optimized at the same time. With an accurate simulation tool we do show the feasibility of such joint optimization and its benefits. We also consider questions of applicability into real networks by testing the stability of our results with poorly estimated channel conditions.
