Relay node placement, which aims to connect pre-deployed sensor nodes to base stations,
is essential in minimizing the costs of wireless sensor networks. In this paper, we formulate …

This work addresses the relay node placement problem in wireless sensor networks. We
consider a scenario in which all sensor nodes stream data towards sink nodes. Additional …

In this paper, we study a problem of designing a multi-hop wireless network for
interconnecting sensors (hereafter called source nodes) to a Base Station (BS), by …

In a heterogeneous wireless sensor network (WSN), relay nodes (RNs) are adopted to relay
data packets from sensor nodes (SNs) to the base station (BS). The deployment of the RNs …

Abstract In Wireless Multimedia Sensor Networks, source nodes send intense multimedia
traffic, under strict quality-of-service requirements, to the base station via resource-limited …

Data collection is usually performed in wireless sensor networks by the sensors relaying
data towards a static control center (sink). Motivated by important applications (mostly …

In this work we consider the relay node placement problem in wireless sensor networks:
where to position a limited number of available nodes that can act as additional relays to …

Wireless Sensor Networks (WSNs) are increasingly used in data-intensive applications such
as microclimate monitoring, precision agriculture, and audio/video surveillance. A key …
