While the paradigm of service oriented architectures and also the concept of service migration has been adapted to wireless sensor networks recently, the consistency demands of stateful service migration have not yet been considered in depth. Many services, for example for the aggregation of data or alarm services, require strict consistency when being migrated from one sensor node to another. In previous papers, we described how atomic commit protocols can be used to guarantee strict consistency of migrated services. Additional communication is required to achieve strict consistency. Therefore we varied the network conditions (i.e. loss rate, density) to determine the best solution in different situations. Finally we designed an adaptive approach which uses the ideal combination of transaction protocol and routing protocol to reduce the communication overhead and save energy to increase the lifetime of wireless sensor network deployments.
