ScatterPastry: An Overlay Routing Using a DHT over Wireless Sensor Networks

Using distributed hash tables (DHTs) over ad-hoc wireless sensor networks (WSNs) has gained a lot of attention in the research arena in last years. In WSN´s world, the most important issue in routing is to gather the routed information coming from sensor nodes to the sink node regardless of the identity of the donating node. The problem in this context is to locate efficiently the sensor node, which holds the data item with the minimum number of intermediate nodes to save network energy. DHTs based on the Internet are used for this purpose. This paper presents a ScatterPastry platform based on pastry DHT as an overlay routing platform for distributed applications over WSNs using Scatterweb nodes, a real-world wireless sensor platform.
