Managing wireless sensor networks in an energy-efficient manner is no mean feat. Management requests and responses create additional traffic in addition to the data issuing from the network's actual sensing application. Effective management therefore requires balancing the need for detailed oversight of the network against the energy consumption of the management system itself. This paper explores whether sending the management data and the sensing data together rather than separately can reduce the management system's energy footprint. From the results of the authors' experiment using BMAC and DYMO on MICAz motes running on TinyOS, they find that their approach does indeed substantially reduce the communication costs of the management system.
