    Data Filtering and Aggregation in a Localisation WSN Testbed

    The main challenge in wireless networks is to optimally use the confined radio resources to support data transfer. This holds for large-scale deployments as well as for small-scale test environments such as test-beds. The authors investigate two approaches to reduce the radio traffic in a test-bed, namely, filtering of unnecessary...

    Performance Evaluation of Reliable Overlay Multicast in Wireless Sensor Networks

    Using multicast communication in Wireless Sensor Networks (WSNs) is an efficient way to disseminate code updates to multiple sensor nodes. For this purpose a multicast protocol has to support bulky traffic (typical traffic pattern for code updates) and end-to-end reliability. In addition, the authors are interested in energy-efficient operations due...
