towards energy efficient xpath evaluation in wireless sensor networks
Using XML as a standardized data exchange format in wireless sensor networks is a means to support more complex data management and heterogeneous networks. Moreover, XML is a key feature towards service-oriented sensor networks. Recent work has shown that XML can be compressed to meet the general hardware restrictions of sensor nodes while still supporting updates. In this work we outline the vision and benefits of XML usage in wireless sensor networks. We further present first evaluation results of an implemented XPath query engine, that is able to evaluate a large set of XPath queries dynamically on XML using sensor nodes.
