DTNSN
Project is concluded as of 2006.Delay Tolerant Networks / Sensor Networks
Wireless sensor networks can be used in a wide range of situations: temperature measurements in buildings, oceanographic studies, wildlife monitoring, rapidly deployed alarm systems. In the DTN/SN project at SICS we use experimental deployments of actual sensor networks to drive our research into communication protocols and their implementation.
Wireless sensor networks consist of large amounts of tiny sensors equipped with a small micro processor, a small radio communication module, an energy source such as a battery, as well as the actual sensors. The sensor nodes are able to form network structures through which sensor readings can be transmitted. In order to prolong the lifetime of the sensor network, developing methods for reducing the power consumption of the sensor nodes is imperative. In the DTN/SN project, we are working with communication protocols and architectures to support energy conservation.
Delay Tolerant Networking (DTN) deals with communication for "challenged networks" which are networks where the communication environment may be far from ideal with high error rates, large delays and sporadic connectivity.
The DTN / SN project is funded by Vinnova, the Swedish Agency for Innovation Systems, and is carried out by people from the Computer and Network Architectures lab at the Swedish Institute of Computer Science in cooperation with our project partners.
