Welcome to the web page of the Sensor Networks Group.

 

 

Our group is located at the Computing Laboratory, University of Oxford.

Technological advances in Micro-Electro-Mechanical Systems (MEMS) are envisaged to allow the dense deployment of nodes with sensing, communication and processing capabilities in large areas for monitoring purposes. Our research objectives are to investigate query processing and data management techniques for wireless ad hoc sensor networks. Due to the limited bandwidth and, in some cases, limited energy resources, it is impossible to forward large amounts of raw sensor data to a powerful gateway node, to be processed there in a centralized manner. This advocates the need for pushing part of the data management services into the network, and performing them at the nodes in a distributed manner. Our research concerns accurate and approximate query processing techniques for sensor networks, as well as packet forwarding techniques for intermittently connected sensors. We explore architectures with both stationary and mobile sensor nodes of various hardware capabilities. We focus our research efforts on three different application scenarios - traffic monitoring, emergency detection and wildlife monitoring.

Our group was established by Niki Trigoni in 2005. Currently, it involves six people working on three projects. More information on these projects can be found on this website.
