Abstract—In wireless sensor networks, asynchronous sleepwake scheduling protocols can significantly reduce energy consumption without incurring the communication overhead for cl...
The emergence of the Semantic Web has led to the creation of large semantic knowledge bases, often in the form of RDF databases. Improving the performance of RDF databases necessit...
Base station location has significant impact on network lifetime performance for a sensor network. For a multihop sensor network, this problem is particular challenging as we need ...
