Device deployment plays a key role in the performance of any large-scale wireless sensor
network (WSN) application. WSN device deployment (ie the numbers and positions of the …

Maximizing network connectivity while maintaining a useful period of lifetime is a
challenging design objective for wireless sensor networks (WSNs). Satisfying such objective …

We study wireless sensor network (WSN) node placement in an environment where RF
signal losses vary with position. This reflects real–world outdoor environments where …

Deploying sensor nodes randomly most of the time generates initial communication hole
even in highly dense networks. These communication holes cannot be totally eliminated …

In a two-tier wireless sensor network (WSN), the relay nodes act as the cluster heads for
data aggregation and dissemination to the base station. It is very crucial and difficult to find …

Device deployment is a major challenge to successful implementation of large scale
wireless sensor network (WSN) applications. The number and positions of devices …

Enhancing the connectivity of wireless sensor networks is necessary to avoid the occurrence
of coverage gaps. In this paper, we aim at improving the network connectivity of a given …

Node placement plays a significant role in the effective and successful deployment of
Wireless Sensor Networks (WSNs), ie, meeting design goals such as cost effectiveness …

In this paper, the problem of relay node placement in heterogeneous wireless sensor
networks (WSNs) is addressed. As all nodes are energy limited, placement strategies aimed …

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 …
