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 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 …

In a wireless sensor network, a sensor measures environmental data. It also relays data for
other sensors. While sensing workload is the same among sensors, relaying workload …

The relay placement problem has been studied extensively in wireless networks. Existing
work typically focuses on connectivity to prolong the network time or to achieve fault …

While a lot of existing research attempts to extend the lifetime of a wireless sensor network
(WSN) by designing energy efficient networking protocols, the impact of random device …

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 …

In a 2D indoor environment, finding the proper location of relay nodes for wireless sensor
networks is a difficult and time consuming job because walls, rooms and restricted areas can …
