We propose a sensornet programming model based on declarative spatio-temporal constraints on events only, not sensors. Where previous approaches conflate events and sensors becaus...
In this paper we present a data dissemination protocol for efficiently distributing data through a sensor network in the face of node and link failures. Our work is motivated by t...
— An important class of queries over sensor networks are network-wide aggregation queries. In this work we study a class of aggregation queries which we refer to as aggregate thr...
Wireless Sensor Networks (WSN) security is an important issue which has been investigated by researchers for few years. The most fundamental security problem in WSN is key manageme...
The many-to-one multihop traffic pattern of Wireless Sensor Networks (WSN) puts a great challenge on enhancing the event-to-sink data delivery throughput. Because, in CSMA/CA dri...
