Pehr Söderman, KTH, will give a talk on the Wireless@kth seed project A DTN/WSN infrastructure for data distribution and environmental monitoring in communication challenged areas.

Abstract:

A Delay Tolerant Wireless Sensor Networks (DT-WSN) is a network which combines ideas from Delay Tolerant Networking (DTN) and Wireless Sensor Networks (WSN). A DT-WSN is a network of constrained devices which can sense the environment, and communicate the information gathered (e.g. temperature, humidity etc.) through wireless links. The data is forwarded, possibly via multiple hops, to some kind of sink node that can either use the data locally, or is connected to other networks through a gateway. The nodes can be stationary or moving; they can be aware of their location or not; and, they can be homogeneous or not. Connectivity between the nodes may be scheduled, intermittent or opportunistic.

In this presentation we give a short introduction to DT-WSN’s and discuss use cases such as the Malawi network. We then introduce the buffer management problem in DT-WSN’s and finally present the SmartGap algorithm which we are working on, an attempt to introduce a Quality of Information focused buffer management algorithm for DT-WSN’s.
