On the Path Processing under Energy Constraints

In wireless sensor networks and pervasive environments situations occur where only one path between a source of raw data and a target requiring processed data is available by topology and/or by the network layer. All nodes - source, target, and relay nodes between them - underly energy constraints. The depletion of the energy of any involved node would disable the network. In consequence, a scheme for the distribution of data processing that minimizes local peaks in energy consumption is needed. This paper introduces solutions for the given problem, where no information about the battery status is available. Furthermore, model modifications to meet more practical situations and the problem of total energy consumption are discussed.
