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 paper, we study the problem of wireless sensor network design by deploying a
minimum number of additional relay nodes (to minimize network design cost) at a subset of …

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 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 …

We are given a set of sensors at given locations, a set of potential locations for placing base
stations (BSs, or sinks), and another set of potential locations for placing wireless relay …

Wireless sensor networks are being geared up for applications that range from consumer
markets to military industries. While the wireless sensors perform the same sensing task …

Wireless sensor networks are gradually employed in many applications that require reliable
and real-time data transmission. As hop count is an important factor affecting end-to-end …

One approach to prolong the lifetime of a wireless sensor network (WSN) is to deploy some
relay nodes to communicate with the sensor nodes, other relay nodes, and the base …

The paper addresses the relay node placement problem in two-tiered wireless sensor
networks. Given a set of sensor nodes in Euclidean plane, our objective is to place minimum …

To eliminate the routing load unbalance among sensor nodes, one approach is to deploy a
small number of powerful relay nodes acting as routing nodes in wireless sensor networks …
