Abstract. A wireless sensor network is a collection of devices limited in lowpowered batteries, processing, communication bandwidth capabilities and low memory availability. Due to...
We present the definition and performance evaluation of a protocol for building and maintaining a connected backbone among the nodes of a wireless sensor networks (WSN). Building ...
There exist several applications of sensor networks where reliability of data delivery can be critical. While the redundancy inherent in a sensor network might increase the degree...

The paper presents a complete framework for spatial indexing support in a distributed setting. We consider a shared-nothing environment where a set of servers provides independent...
To increase the lifespan of wireless sensor networks (WSN) and preserve the energy of sensors, data aggregation techniques are usually used. Aggregation can be seen as the process ...
